When I source 3,5-Dichlorophenylboronic acid, CAS 67492-50-6, I treat identity confirmation, specification control, documentation, packaging, and delivery planning as equally important. This compound is an aromatic boronic acid building block used in synthetic chemistry, particularly in palladium-catalyzed cross-coupling research and development. Its commonly referenced molecular formula is C6H5BCl2O2, with a molecular weight of approximately 190.82 g/mol. Maison Chemical supports B2B buyers by discussing the required grade, quantity, analytical documents, packaging, and delivery conditions before an order is finalized.

I prepared this guide for pharmaceutical and agrochemical research teams, custom synthesis companies, university laboratories, process-development groups, and chemical distributors. It is also relevant to purchasing managers who need to compare multiple suppliers for a specialty organic boronic acid. The guide focuses on procurement decisions rather than presenting a laboratory synthesis procedure.
Buyers may need only a small quantity for route scouting, while process-development or distribution projects may require repeated lots. These purchasing situations require different controls for packaging, lot reservation, analytical testing, and delivery planning. I therefore recommend defining the intended use and expected annual demand before requesting a final quotation.
3,5-Dichlorophenylboronic acid is an organoboron compound containing a phenyl ring, two chlorine substituents, and a boronic acid functional group. The CAS Registry Number used for product identification is 67492-50-6. The boronic acid group can participate in carbon–carbon bond-forming chemistry, including Suzuki–Miyaura-type coupling workflows, subject to the reaction system and substrate combination selected by the chemist.
For procurement purposes, the chemical name and CAS number should be checked together. A name-only search can create confusion between 2,4-, 2,5-, 3,4-, and 3,5-dichlorophenylboronic acid isomers, which may not deliver equivalent reaction behavior. I recommend matching the supplier’s label, specification sheet, SDS, and analytical report to the same CAS number before material release.
The first verification points are product name, CAS number, molecular formula, molecular weight, and structural position of the chlorine substituents. A buyer should also confirm whether the quoted material is supplied as the free boronic acid and whether any special form, stabilizer, or handling note applies. These details are important when the material is entered into an electronic procurement or laboratory inventory system.
An assay specification should be agreed in writing rather than assumed from a catalog description. Depending on the application, the buyer may also request limits for related organic impurities, inorganic residues, water content, residual solvents, and other process-related substances. I advise setting only the tests that are relevant to the intended reaction and downstream quality requirements, because unnecessary testing can affect cost and lead time.
Appearance is commonly recorded as part of incoming inspection, although visual appearance alone cannot confirm chemical purity. The supplier should provide suitable handling information through an SDS, along with storage guidance and package labeling. For regulated or quality-sensitive projects, buyers may additionally request a lot-specific Certificate of Analysis, analytical method information, origin details, and a statement regarding the manufacturing or packing site.
Maison Chemical can review these requirements during quotation preparation. I do not recommend treating a generic technical data sheet as a substitute for batch documentation when the material will enter a validated process or a formal quality system. The exact document package should be agreed before purchase, especially for export orders.
For early-stage research, the main priorities are correct identity, suitable purity, practical pack size, and fast availability. A small pack may reduce inventory exposure while the chemistry is being evaluated. However, I still recommend requesting a CoA or equivalent quality document if the results will guide later scale-up decisions.
For process development, lot-to-lot consistency and impurity control become more important than the lowest initial price. The buyer should compare the analytical profile of development material with the profile expected for future production lots. It is also useful to discuss whether the supplier can support repeat orders using an agreed specification and consistent packaging configuration.
Distributors and resellers should evaluate labeling, outer packaging, export documentation, shelf-life information where applicable, and the supplier’s ability to support planned replenishment. They should also confirm whether the product is available from stock or produced after order confirmation. A clear distinction between ready inventory and scheduled production helps reduce avoidable delivery uncertainty.
Maison Chemical supply professional and honest service.
I recommend comparing suppliers using the same written inquiry. For example, ask each supplier to quote the same quantity, grade, packaging format, destination, and document package. This makes the comparison more meaningful than evaluating unit price alone.
The price of 3,5-Dichlorophenylboronic acid can vary according to quantity, purity target, packaging, production status, analytical requirements, and destination. A small research pack may have a higher price per gram than a larger commercial quantity because fixed handling and documentation costs are distributed over less material. I recommend asking for at least two quantity tiers when planning future consumption.
MOQ is not necessarily a fixed technical property of the chemical; it is a commercial condition that may depend on stock and packaging. Lead time also varies between ready stock, repacking, fresh production, and additional quality testing. Buyers should request a written estimate in business days or calendar days, and should ask whether the estimate begins after purchase order approval, payment, or technical confirmation.
As a practical planning reference, I advise allowing at least 2–3 business days for internal document review before dispatch when the order requires a formal approval cycle. This is a planning recommendation rather than a guaranteed delivery period. The final timeline should be confirmed against the destination, shipping method, quantity, and current inventory position.
I also recommend checking how the supplier manages specification changes, packaging changes, and out-of-stock situations. A responsive supplier should identify what is confirmed, what is estimated, and what still requires technical review. This transparency is often more useful than an aggressive but unsupported delivery promise.
One common mistake is ordering by chemical name without confirming the CAS number and substitution pattern. Another is comparing prices from suppliers that are quoting different purity levels, pack sizes, or document packages. Buyers may also overlook the difference between a product that is physically in stock and one that requires a new production campaign.
A further risk is requesting an unusually broad analytical package without determining whether the tests are necessary. Excessive requirements can increase cost and delay release, while insufficient requirements may create problems during incoming inspection. I recommend involving both the chemist and purchasing team when finalizing the specification.
Maison Chemical supplies and exports organic boronic acid products, including 3,5-Dichlorophenylboronic acid CAS 67492-50-6, for customers evaluating research, development, and commercial sourcing requirements. I can help organize the initial product confirmation, specification discussion, quotation, packaging review, and shipment coordination. The available options should be confirmed according to quantity, grade, current inventory, destination, and documentation needs.
For a more efficient inquiry, send the CAS number, required quantity, target specification, preferred packaging, destination country, requested delivery window, and document requirements. If you are still comparing grades, describe the intended application and I can help identify which technical questions should be resolved before ordering. This approach reduces ambiguity and makes the quotation more useful for internal approval.
The best way to purchase 3,5-Dichlorophenylboronic acid CAS 67492-50-6 is to verify identity first, define application-relevant specifications, and compare suppliers on documentation, packaging, delivery, and service as well as price. The compound’s role as an aromatic boronic acid building block makes correct isomer selection especially important for synthetic chemistry projects. A written specification and batch-specific documentation provide a stronger basis for approval than a product name alone.
My recommended next step is to prepare a standardized RFQ containing the CAS number, quantity, purity requirement, packaging, destination, required documents, and target delivery date. Send that information to Maison Chemical for a tailored quotation and availability review. Once the product documents and commercial terms meet your requirements, complete your internal supplier approval and confirm the purchase order with the agreed specification.
