Phenylboronic acid CAS 98-80-6 is an important boronic acid intermediate used mainly in organic synthesis, especially palladium-catalyzed Suzuki–Miyaura cross-coupling reactions. Its molecular formula is C6H7BO2, and its molecular weight is approximately 121.93 g/mol. When purchasing this material, I recommend evaluating identity, assay, impurity profile, packaging, documentation, logistics, and supplier responsiveness together rather than selecting only by price.
At Maison Chemical, we support B2B buyers sourcing Phenylboronic acid for pharmaceutical intermediates, agrochemical research, specialty chemicals, and laboratory or process development applications. We can discuss product specifications, batch documentation, packaging requirements, export arrangements, and purchasing quantities according to the buyer’s project stage. Final availability, lead time, and commercial terms should always be confirmed against the requested specification and destination.
This guide is intended for procurement teams, R&D chemists, process chemists, quality managers, distributors, and manufacturers evaluating Phenylboronic acid CAS 98-80-6. It is useful for both initial supplier screening and repeat purchasing programs. The same product may require different documentation or packaging depending on whether it is used for laboratory development, scale-up, commercial production, or distribution.
Buyers should also distinguish between a material suitable for exploratory chemistry and one intended for a controlled manufacturing process. A small research order may focus on availability and basic analytical data, while a production buyer may require consistent batch quality, change-control communication, traceability, and a defined logistics plan. I recommend establishing these requirements before requesting quotations.
Phenylboronic acid is an organoboron compound containing a phenyl group bonded to a boronic acid functional group. The commonly referenced identification details are CAS number 98-80-6, formula C6H7BO2, and molecular weight about 121.93 g/mol. These identifiers should appear consistently across the quotation, specification sheet, safety data sheet, certificate of analysis, shipping documents, and purchase order.
The compound is widely valued because the boronic acid group can participate in carbon–carbon bond-forming chemistry. In Suzuki–Miyaura coupling, it is commonly used with an aryl or vinyl halide and a suitable catalyst system, although the exact reaction conditions depend on the substrate and process design. Its role as a synthetic building block makes impurity control and lot-to-lot consistency important for downstream chemistry.
Phenylboronic acid is often purchased in different commercial quantities, but the quantity alone does not define suitability. Buyers should specify whether the material is intended for screening, method development, pilot work, or routine manufacturing. A material selected for process use may need a tighter internal specification than a material used for early-stage reaction discovery.
Typical purchasing discussions may include appearance, identification, assay, related substances, water or residual solvents, and packaging condition. I advise buyers not to assume that a stated “high purity” grade has the same test method or acceptance limits across suppliers. The supplier should provide the actual specification and representative batch documentation for review.
| Purchasing item | What to confirm |
|---|---|
| Identity | CAS 98-80-6, chemical name, formula, and molecular weight |
| Quality | Assay method, purity limit, related substances, and appearance |
| Documentation | Certificate of analysis, safety data sheet, specification, and traceability information |
| Packaging | Net weight, inner container, outer protection, labeling, and batch identification |
| Logistics | Incoterm, shipping route, export documents, lead time, and destination requirements |
For a first evaluation, I suggest requesting a recent certificate of analysis rather than relying only on a product webpage. The certificate should identify the batch, test date, analytical methods where applicable, and reported results. If a buyer has a validated method or a critical impurity concern, that requirement should be communicated before the quotation is finalized.
For medicinal chemistry and pharmaceutical intermediate development, buyers commonly focus on reliable identity, reproducible assay, manageable impurity levels, and documentation that supports internal qualification. For process chemistry, the impact of trace impurities on catalyst performance, conversion, isolation, and downstream purification may be more important than a headline purity number. For distributors, packaging integrity, labeling consistency, shelf-life information, and export support may carry greater weight.
These questions help prevent a common sourcing error: comparing quotations that are not based on equivalent specifications. A lower unit price may not represent better value if it excludes required testing, special packaging, documentation, or delivery terms. I recommend comparing the complete delivered cost and qualification workload.
A qualified supplier should be able to explain how product identity and quality are controlled. Ask for the current specification, safety data sheet, certificate of analysis format, batch traceability approach, and retest or shelf-life policy where applicable. Buyers should also ask how specification changes, raw material changes, and manufacturing-site changes are communicated.

Documentation should be consistent across commercial and technical teams. The product name, CAS number, batch number, net quantity, and packaging description should not conflict between documents. When the material is intended for a regulated or quality-sensitive project, the buyer may also need to complete a supplier questionnaire or technical agreement.
Supplier evaluation should cover more than whether material is listed in a catalog. I recommend asking about available commercial quantity, standard batch size, production scheduling, reserve-stock policy, and the ability to support repeat orders. A supplier that provides clear answers early can reduce avoidable delays during purchasing and qualification.
At Maison Chemical, we approach inquiries by first confirming the required grade, quantity, destination, packaging, and documentation. We can then coordinate a quotation and clarify whether the request is for a sample, development order, regular shipment, or larger supply program. Any manufacturing, testing, or export details are confirmed according to the specific order rather than presented as blanket guarantees.
Phenylboronic acid pricing depends on several variables, including quantity, specification, packaging, testing requirements, shipping destination, and market conditions. Buyers should request quotations that clearly state the currency, Incoterm, validity period, payment terms, and whether transport or export charges are included. Comparing only the price per kilogram can produce an inaccurate sourcing decision.
Minimum order quantity is usually connected to packaging, production planning, and shipment economics. A development buyer may need a smaller quantity, while a manufacturing buyer may request a scheduled supply arrangement. Lead time should be separated into stock availability, production time, quality release time, and transportation time; these stages are not always interchangeable.
As a practical data point, buyers should confirm whether the quoted quantity is expressed in grams, kilograms, or another unit before approving an order. They should also verify the requested delivery window in calendar days rather than assuming that a supplier’s production lead time includes international transit. For temperature, humidity, and handling requirements, the current safety data sheet and supplier shipping instructions should take precedence over general assumptions.
Packaging should protect the material from contamination, moisture exposure, physical damage, and labeling loss during storage and transport. The buyer should confirm inner and outer packaging materials, net weight per container, batch labeling, tamper evidence where required, and whether customized packaging is available. For larger shipments, palletization and carton configuration should be agreed before dispatch.
Storage and handling instructions must be reviewed in the supplier’s current safety data sheet. Chemical classification, transport status, labeling obligations, and import requirements can vary according to jurisdiction, formulation details, quantity, and shipping mode. I recommend that the importer or designated regulatory team verify local requirements before placing the order, especially for cross-border shipments.
Another frequent mistake is delaying technical communication until after the purchase order is issued. If a buyer needs a specific test method, retest period, packaging format, or change-notification process, that information should be included in the initial inquiry. Early clarification usually makes the quotation more accurate and reduces the risk of rework.
A strong inquiry enables a supplier to respond with useful commercial and technical information. I recommend including the product name, CAS number, intended application, requested quantity, target specification, destination country, packaging preference, required documents, and desired delivery schedule. If the material will enter a validated process, identify any critical quality attributes or customer-specific requirements.
The best Phenylboronic acid CAS 98-80-6 supplier is not necessarily the one offering the lowest initial price. A suitable B2B source should provide clear identity information, fit-for-purpose specifications, traceable documentation, secure packaging, realistic lead-time communication, and support for the buyer’s destination and application. The purchasing decision should be based on total supply risk and technical suitability.
To begin, send Maison Chemical your required quantity, target specification, application stage, destination, packaging preference, and documentation needs. We can use those details to prepare a more relevant quotation and identify the information needed for internal supplier approval. Before final purchase, review the agreed specification, COA requirements, shipping terms, and compliance documents with your quality and regulatory teams.
