A Buyer’s Guide to 4-Bromophenylboronic Acid CAS 5467-74-3: Uses, Specifications, and Sourcing

Key Takeaways

• 4-Bromophenylboronic acid, CAS 5467-74-3, is an aromatic boronic acid with both a boronic acid group and a bromine substituent.
• Its two functional handles make it useful as a building block in organic synthesis, including Suzuki–Miyaura coupling and sequential functionalization strategies.
• Confirm the required assay, analytical documentation, packaging, and delivery terms against your own process before comparing quotations.
• Maison Chemical can discuss product requirements and sourcing options with B2B buyers; availability, specifications, and lead time should be confirmed for each inquiry.

Who This Guide Is For

This guide is for procurement teams, chemical distributors, and research or process chemists evaluating 4-Bromophenylboronic acid for a specific project. It explains the compound’s role, the specification questions that matter, and how to structure a supplier inquiry. It is not a substitute for a project-specific assessment of reaction conditions, safety, or regulatory obligations.

What Is 4-Bromophenylboronic Acid?

4-Bromophenylboronic acid is an arylboronic acid in which a boronic acid group and a bromine atom occupy opposite positions on a benzene ring. Its CAS number is 5467-74-3, its molecular formula is C₆H₆BBrO₂, and its molar mass is approximately 200.83 g/mol. The compound is also described as 4-bromobenzeneboronic acid.

For synthesis planning, its key feature is the presence of two different reactive sites. The boronic acid group can participate in carbon–carbon bond-forming reactions, while the aryl bromide may provide a separate coupling handle under suitable conditions. Whether both sites can be used selectively depends on the substrate, catalyst system, reaction sequence, and process conditions.

Uses and Application Matching

Suzuki–Miyaura Coupling

As an arylboronic acid, the compound can serve as an aryl donor in Suzuki–Miyaura coupling with an appropriate organic halide or pseudohalide. This makes it a potential intermediate for preparing substituted biaryl compounds and other aromatic structures. A chemist should confirm compatibility with the planned catalyst, base, solvent, and reaction partners rather than assuming one set of conditions will work across projects.

Sequential Functionalization

The para-bromine substituent gives the molecule a second point for possible downstream chemistry. In some synthesis designs, teams may use the boronic acid group in one transformation and retain the bromide for a later step, or investigate the reverse order. Selectivity is not automatic, so reaction screening and analytical confirmation may be needed before a route is scaled.

Research and Intermediate Sourcing

Buyers may encounter this compound in medicinal chemistry, materials research, or custom organic synthesis workflows where substituted aromatic intermediates are required. The exact fit depends on the target structure and the route under development. For early-stage work, a smaller quantity may support evaluation; for process or production planning, buyers should also assess repeatability, packaging, and supply continuity.

Specifications and Documentation to Review

A product name and CAS number are important identity checks, but they do not define every quality attribute a project needs. Before purchase, align the requested grade and acceptance criteria with your internal method, intended use, and applicable handling procedures. Ask the supplier which values are established product specifications and which are subject to confirmation for a particular batch.

Do not treat an illustrative purity threshold as a universal requirement. A project may need a different limit or additional controls for water content, residual solvents, or trace impurities, depending on its analytical capabilities and downstream sensitivity. Request the available batch documentation before placing an order if those attributes affect release or process performance.

Buyer Selection Framework

1. Define the Application and Grade

Start by sharing the intended use at a level that helps the supplier recommend a suitable grade and quantity. State whether the material is for laboratory evaluation, route development, process qualification, or a recurring manufacturing need. If your organization has a written specification, send it with the inquiry rather than relying on a general product description.

2. Compare Specifications on the Same Basis

When reviewing offers, check that purity methods, reporting limits, and document formats are comparable. A percentage without its test method or acceptance basis may not be enough to assess whether two quotations meet the same requirement. Clarify whether the quoted specification applies to the current batch, a routine product standard, or a target that still requires confirmation.

3. Match Quantity to Project Stage

Request a quotation for quantities that reflect your actual evaluation plan, and distinguish sample needs from repeat orders. As an example of quote-sizing—not a statement of stock availability—you might request pricing at 100 g, 1 kg, and 5 kg to understand how pack size affects the commercial offer. Confirm the minimum order quantity, whether split packaging is possible, and whether the quote changes with quantity.

4. Confirm Timing and Delivery Terms

Lead time depends on availability, order quantity, documentation needs, and shipping destination, so obtain a current estimate rather than relying on a general assumption. Ask when the lead-time estimate begins, what delivery terms are quoted, and whether any export or transport documents are needed for your destination. If the material is required for a scheduled campaign, allow time for internal qualification and incoming inspection.

Pricing, MOQ, and Lead-Time Considerations

The quoted price for 4-Bromophenylboronic acid may vary with requested quantity, specification, packaging, documentation, and destination. A low unit price is not necessarily the lowest total procurement cost if the offer does not meet your assay or documentation requirements. Compare quotations using the same quantity basis, delivery terms, and specification, and confirm whether taxes, freight, or other charges are included.

Minimum order quantity and lead time should be confirmed directly for the requested grade and destination. For a first purchase, buyers can ask whether a smaller evaluation quantity is available before committing to a larger order. For repeat demand, discuss forecast volumes and expected ordering frequency so the supplier can respond with relevant sourcing options without implying guaranteed future availability.

Supplier Evaluation Checklist

• Can the supplier confirm the chemical identity and provide a specification for the offered material?
• Which batch-specific documents are available, and when will they be provided?
• Are packaging, quantity, minimum order, and lead time clearly stated in the quotation?
• Can the supplier confirm shipping terms and documentation requirements for your destination?
• Is there a clear process for addressing specification questions or nonconformities?

For Maison Chemical, buyers can submit the required quantity, target specification, destination, and intended use for review. We can discuss the product and sourcing requirements and confirm the details that apply to the specific inquiry. Product availability, batch documentation, packaging, and timing should be verified before purchase.

Conclusion: How to Source the Right Material

4-Bromophenylboronic acid CAS 5467-74-3 is a useful bifunctional aromatic building block when a synthesis route needs a boronic acid handle alongside an aryl bromide. The right buying decision depends on matching the offered identity, assay, documentation, quantity, and delivery plan to your application—not on the compound name alone. Define your acceptance criteria, request batch-relevant evidence, and compare supplier quotations on consistent terms.

To move forward, send Maison Chemical your target quantity, required specification, destination, and project stage. We can then review the sourcing request and confirm applicable product and commercial details for your evaluation.
