| Property | Description / Manufacturer Commentary |
|---|---|
| Product Name | 1-Bromodibenzofuran |
| IUPAC Name | 1-Bromodibenzofuran |
| Chemical Formula | C12H7BrO |
| Synonyms & Trade Names | 1-Bromo-dibenzofuran, DBF-Br (common abbreviation within technical circles), no standard trade names widely adopted in the commodity sector. Internally, batch tracking relies on IUPAC naming and structural identifiers to avoid trade name confusion during inventory management and quality control releases. |
| HS Code & Customs Classification | The commodity code assigned in most jurisdictions is typically within chapter 2932 (heterocyclic compounds with oxygen hetero-atom(s) only, nucleic acids and their salts). HS code assignment remains region-specific since customs authorities sometimes require clarification on brominated aromatics, especially when impurity profiles or restricted substance thresholds trigger extra inspection. Production batches destined for export are documented with their specific HS code according to the destination country's integration with WCO Harmonized System update schedules. This ensures unambiguous customs declaration for regulatory and logistics compliance. |
Industrial Context
Within manufacturing, 1-Bromodibenzofuran is isolated as an aromatic brominated compound tracked by structural and batch-purity identifiers. End-users, particularly in pharmaceutical and materials research applications, verify the presence of positional isomeric purity (distinguishing 1-bromo from other possible bromodibenzofurans) using both spectroscopic and chromatographic in-process controls. In commercial scale, the attribute of primary industrial interest relates to grade-dependent purity: the final release standards and impurity profile control depend on application (intermediate vs. reference standard grade) and the downstream customer’s tolerance for halogenated byproducts.
Raw material selection targets low-halogen background inputs to minimize formation of polybrominated species. Bromination route selection weighs yield, positional selectivity, and downstream ease of purification—these decisions are not static, but adapt to changes in cost, regulatory status of reagents, and the demonstrated process reproducibility within each campaign. Key control points include stoichiometry of brominating agents, solvent quality, and temperature maintenance, with focus on limiting dibenzofuran oxidation and off-target aromatic halogenation.
Impurity generation is characteristically observed from over-bromination, incomplete reactions, or trace “carry-through” from dibenzofuran stocks with non-compliant purity (notably, dibenzofuran supplied for industrial uses may contain related fused-ring aromatic impurities, which are tracked throughout production to avoid exceeding customer-defined limits). Purification strategies prioritize a combination of phase separation, solvent-controlled crystallization, and adsorption-based chromatographic removal of isomeric or multi-brominated fractions when end-use purity demands exceed technical grade specifications.
Batch consistency involves real-time verification of conversion, purification yield, and conformance with internal control standards, which may be recalibrated per customer-driven feedback loops or in response to regulatory audit findings. Documentation reflects the exact process route, batch-specific impurity profiles, and shipment-specific declarations with respect to HS code, to avoid customs or end-user compliance issues.
Technical Properties, Manufacturing Process & Safety Guidelines for 1-Bromodibenzofuran
Physical & Chemical Properties
Physical State & Appearance
1-Bromodibenzofuran is handled as a crystalline solid in most industrial settings. The appearance can range from off-white to pale yellow, with grade and storage conditions influencing hue intensity. Any pronounced color development over time may indicate degradation or contamination. Industrial batches are odorless or only very slightly aromatic, since pure material contains little to no volatile impurities.
Melting & Boiling Point
The melting and boiling points are defined by both grade and the presence of low-level organics or residual starting materials. Variation here reflects purity: lower melting or boiling ranges often signal impurity entrainment or incomplete purification. Exact values require analytical confirmation per batch, as specification limits are agreed with each customer.
Flash Point & Density
Measuring flash point and density is necessary for storage and transport compliance. Flash point assessment supports safe handling protocols, especially in bulk storage environments. Bulk density fluctuates with particle size distribution and moisture content, both tightly controlled by process conditions and drying parameters. Specification tables distinguish by application or grade.
Chemical Stability & Reactivity
On the plant floor, the main threats to product integrity come from light, accidental contact with acids or bases, or prolonged high temperature exposure. Batch stability depends on storage discipline. The substance resists moderate oxidative or reductive conditions but participates in halogen exchange or coupling reactions under catalytic conditions. Instability manifests through color change or assay drift, requiring prompt attention to prevent out-of-specification shipments.
Solubility & Solution Preparation
Solubility in organic solvents such as DCM, toluene, or THF is grade- and application-sensitive. Water solubility remains negligible across all grades. Dissolution characteristics depend on particle size, residual solvents, and temperature, which must be controlled for formulating intermediates or active synthesis steps. Best practice is to avoid strong agitation if undissolved powder is present, reducing dust and exposure risk.
Technical Specifications & Quality Parameters
Specification Table by Grade
Customer demand dictates the allowable impurity content, color, physical profile, and residual solvent content. Each grade—whether standard, high-purity, or custom—carries its agreed specification window for main assay (typically by HPLC/GC), maximum allowable halide residues, and water content (KF titration for sensitive formulations). Final specification is set by joint manufacturer-customer protocol and end-use sector requirements.
Impurity Profile & Limits
Typical impurities originate from incomplete bromination, starting reagent carryover, and side reactions during cyclization. Key trace components include dibenzofuran, dibromodibenzofuran, and related halogenated aromatics. Limit definitions follow risk assessment for the customer’s downstream step. Process control at both bromination and purification stages minimizes out-of-spec impurity profiles.
Test Methods & Standards
Analytical protocols depend on grade, with release testing typically covering identity (NMR/IR), assay (GC, HPLC), and chromatographic impurity profiling. Water by Karl Fischer, and residual solvents by GC, support sensitive applications. Internal statistical Quality Control assesses batch-to-batch reproducibility and flags deviation for process review.
Preparation Methods & Manufacturing Process
Raw Materials & Sourcing
Raw material selection focuses on dibenzofuran and high-purity bromine sources. Supply logistics prioritize stable provenance and traceability, with each new lot of starting materials qualified by lab-scale check synthesis prior to main batch commitment. Raw material purity is crucial—downstream purification burden increases if input quality falls.
Synthesis Route & Reaction Mechanism
Most industrial synthesis relies on direct monobromination of dibenzofuran under controlled halogenation conditions. Catalysts or additives are selected based on cost, reaction selectivity, and safety risk. Reaction temperature and addition rate are tightly monitored to suppress over-bromination and unwanted side-chain products. Continuous or semi-batch operation is standard at scale.
Process Control & Purification
Critical control points include bromine feed management, reaction exotherm dissipation, and rapid work-up to avoid secondary by-product formation. Purification revolves around staged crystallization and solvent wash or chromatographic fractionation, the choice informed by batch size and downstream purity needs. Any deviations in process analytics trigger corrective review prior to bulk release.
Quality Control & Batch Release
Each batch passes through predefined analytical checkpoints, including in-process purity checks and end-point adjustments. Batch release to inventory or customer occurs only after full analytics confirm all specification criteria. Deviations result in either rework or off-grade allocation, depending on the customer’s risk tolerance and product end use.
Chemical Reactions & Modification Potential
Typical Reactions
The main value of 1-Bromodibenzofuran lies in its suitability for metal-catalyzed cross-coupling reactions (e.g., Suzuki, Stille). Reaction performance varies with halide purity, level of trace metals, and crystalline structure, all monitored at manufacturing. Common transformations include arylation, amination, and borylation, each optimized by specialist customers for target molecule synthesis.
Reaction Conditions (Catalyst, Temperature, Solvent)
Palladium-catalyzed coupling forms the core downstream application. Best practice involves oxygen-free environments and anhydrous solvents, as moisture and air degrade catalyst activity and yield. Specifying the required grade at order placement ensures that product quality aligns with expected reactivity and customer process efficiency.
Derivatives & Downstream Products
End users convert 1-Bromodibenzofuran into a range of advanced materials, pharmaceutical intermediates, or specialty dyes. The transformation path is largely grade- and region-specific, with some customers dictating ultra-purity, others prioritizing cost efficiency or scale. By-product and derivative tracking forms part of the customer feedback loop to enhance upstream impurity management.
Storage & Shelf Life
Storage Conditions (Temperature, Humidity, Light Avoidance, Gas Protection)
Best results occur when product is kept in sealed, opaque containers at controlled room temperature, away from sources of direct heat and light. Moisture and oxygen exposure lead to slow degradation, visible as coloration or assay fall-off. Bulk storage must deploy desiccants or inert gas blanketing for unstable grades.
Container Compatibility
Product compatibility has been validated for glass, HDPE, and certain fluoropolymer linings. Metal fittings should be avoided unless passivated, as trace acids can form and corrode container welds or lids. Customers requiring bespoke packaging can request test reports for alternate container types.
Shelf Life & Degradation Signs
Typical shelf life is contingent on grade, packaging standard, and storage compliance. Shelf stability is tracked by periodic retention sampling. Early signs of degradation include color change, increased extractables in solvent, or trending impurities in analytic tests. Any out-of-spec signals from shelf-life checks trigger internal investigation.
Safety & Toxicity Profile
GHS Classification
Hazard classification can vary with jurisdiction and product grade, especially for bulk vs. sample packaging. Labeling reflects current national regulations plus available toxicity data from industrial use and published literature.
Hazard & Precautionary Statements
Risk stems from dust inhalation, skin contact, and accidental release during powder handling. Staff training in powder containment, PPE usage, and washing after handling mitigates exposure risk. Typical recommendations include use of dust masks, safety goggles, and chemical-resistant gloves in production and packaging areas. All accidental releases are recorded and investigated as part of continuous safety review.
Toxicity Data
Available data on acute and chronic toxicity is incomplete but points to low acute oral and dermal toxicity at expected handling concentrations. Occupational exposure guidelines draw from broader halogenated aromatic policies, emphasizing minimal inhalation exposure and skin barrier protection.
Exposure Limits & Handling
Engineering controls such as local exhaust ventilation, closed transfer systems, and process automation form the foundation of exposure management. Product traceability, batch coding, and training logs ensure compliance with both in-house and regulatory standards. Where exposure incidents occur, medical review and re-training follow.
Supply Capacity & Commercial Terms for 1-Bromodibenzofuran
Production Capacity & Availability
1-Bromodibenzofuran production typically draws from continuous campaigns, batch production or campaign mode, depending on plant utilization and demand in the fine chemicals sector. The usable output hinges on reactor size, equipment material compatibility, and downstream purification bottlenecks. Commercial scale stems from a combination of custom-manufactured lots and semi-continuous production slots tied to related dibenzofuran derivatives. Available stock levels vary based on customer forecast sharing and prior notice for toll campaigns. Sudden spot inquiries, especially for higher grades, face dependency on existing campaigns or require new slot scheduling. High purity and regulatory-sensitive applications demand additional lead times for batch-specific validation.
Lead Time & Minimum Order Quantity (MOQ)
Lead time revolves around batch campaign scheduling, current production queue, in-process QMS protocols, and customer-specific documentation. Standard industrial grade MOQs typically match full batch sizes set by reactor charge (often 25–200 kg, depending on installation), while research grades can support smaller packaging as low as 1 kg, subject to line decontamination and cross-batch control protocols. Orders requiring unique cleaning validation, certificate of analysis per lot, or customized release testing may encounter further time extension.
Packaging Options
Usual packaging comprises HDPE drums, lined fiber kegs, or glass bottles for R&D quantities. For export and sensitive applications, tamper-evident seals and additional inert gas blanketing are employed. Packaging material selection and unit size depend on grade requirements, destination market, and regulatory documentation needs, particularly for high-purity or pharmaceutical-intermediate grades. Customer-specific requests, such as UN-certified containers, are available on negotiation.

What is the chemical purity specification of 1-Bromodibenzofuran available for research use?
Understanding the Purity Standard from the Production Line
At our plant, producing 1-Bromodibenzofuran to research-grade standards isn’t just about hitting a number—it comes down to the discipline in our process, the consistency of our purification steps, and the rigor of the analytical controls we apply to every batch. For researchers, purity isn’t a marketing slogan. It is fundamental to reliable experiments and dependable results. Research in fields like synthetic organic chemistry, materials science, or pharmaceuticals relies on traceable, verifiable chemical quality. That’s why we prioritize transparency in how we define and confirm every specification provided with each lot.
Purity Benchmarks and Analytical Testing
Our production protocols for 1-Bromodibenzofuran consistently achieve a chemical purity of not less than 98% based on HPLC and/or GC analysis. We do this by taking raw materials from strictly qualified sources and implementing controlled bromination and purification sequences in a dedicated reactor system. Post reaction, each batch moves through a multistep purification involving solvent washes and vacuum distillation, producing an off-white to light beige solid that we rigorously test against our in-house reference standards.
Routine batch-release QC data includes HPLC purity, GC area percentage, and where needed, NMR analysis to confirm identity and exclude positional isomers. We include reports on additional trace impurities—whether unreacted dibenzofuran, polyhalogenated byproducts, or solvent residuals—when these are above threshold values. These steps align with established norms in academic and industrial research, so users know the material’s integrity suits both exploratory and more demanding synthetic work.
Why 98% Purity Matters
In our experience, pushing beyond 98% purity sees diminishing returns for most research-scale reactions versus the cost and yield tradeoff on a pilot reactor. Even trace contaminants can catalyze side reactions or obscure analytical data, so each sub-percentage point matters. Institutions and R&D labs often request a certificate of analysis tied to batch-specific data; we provide this for every shipment. Some applications—extended ligand design, photophysical studies, or scale-out to GMP synthesis—demand even tighter impurity profiles. For those, our technical team collaborates with clients on custom purifications, supported by advanced analytics such as LC-MS or HRMS.
Maintaining Quality Throughout Packaging and Shipping
Protecting the purity we manufacture means more than just what happens inside the plant. We use air-tight glass bottles or inert-lined high-density polyethylene containers, depending on shipping needs. All packaging is washed, dried, and handled under low-moisture conditions. Labels document batch numbers and expiration dates for full traceability. For clients with unique volume requirements or environmental controls, we can customize packing and shipment strategies to fit lab or process scale.
Supporting Your Research
Our approach extends beyond delivering a drum or bottle of 1-Bromodibenzofuran. As the original manufacturer, we track every synthesis back to the starting raw material, so our technical support staff can answer inquiries about residuals, reproducibility, or alternate purification requests. We provide supplementary analytical data on request, not just the minimal paperwork. For teams scaling from milligram trials to multi-kilo projects, this level of access establishes the trust and reliability needed in cutting-edge research or new material development.
Is 1-Bromodibenzofuran available in bulk quantities, and what are the lead times for procurement?
Supplying high-purity 1-Bromodibenzofuran on an industrial scale requires more than just equipment and raw materials. Meeting bulk demand means our process must run consistently, with direct oversight on sourcing, reaction control, and quality assurance. This is the only way to guarantee a stable supply, batch-to-batch reproducibility, and efficient lead times.
Straight Talk on Bulk Inventory
We maintain multi-kilogram to ton-scale synthesis capacity for 1-Bromodibenzofuran. Inventory positions keep pace with orders from the pharmaceutical, agrochemical, and advanced material sectors. Routine production runs ensure stock replenishment, preventing bottlenecks at critical stages. If our standard inventory occasionally falls short of immediate demand, we can scale up on short notice, drawing upon secure raw material lines and experienced staff.
Production Timelines: Fact-Based Logic
Manufacturing lead time for 1-Bromodibenzofuran varies depending on the size of a single order and the timing relative to current production slots. We’ve honed our process over years, so turnaround for standard batch sizes sits around 2–4 weeks from confirmed order to shipment. This estimate covers internal QA, analytical release, and robust packaging. If a project involves exceptionally large quantities or customer-directed analysis, timelines may extend up to six weeks, but our technical team works directly with buyers to optimize scheduling without sacrificing product integrity.
What Affects Lead Time Most?
Global availability of starting materials has improved, yet spikes in demand for related intermediates occasionally affect our supply chain. With decades of in-house chemical synthesis experience, we avoid surprise disruptions by sourcing reactants from vetted suppliers and maintaining strategic reserves onsite. Manufacturing bottlenecks rarely happen since our reactors and filtration systems run in parallel, reducing risks of downtime. Shipping constraints may emerge during peak global freight periods, but with proper forecasting, cargo usually ships to customers promptly after final QC release.
