I recommend choosing a supplier that can verify the identity of 3,4-Dichlorophenylboronic acid CAS 151169-75-4, provide batch-specific quality documentation, and support your intended Suzuki coupling or research workflow. The correct supplier should also demonstrate practical control over packaging, shipment, communication, and repeat supply rather than offering only a low initial price. At Maison Chemical, we evaluate this type of inquiry around product identity, documentation, application fit, and commercial requirements so buyers can make a more informed sourcing decision.

3,4-Dichlorophenylboronic acid is an aryl boronic acid used as a coupling partner in synthetic chemistry, including Suzuki–Miyaura coupling research. Its stated CAS number is 151169-75-4, and its molecular formula is commonly represented as C6H5BCl2O2, with a calculated molecular weight of approximately 190.82 g/mol. These identifiers provide a useful starting point, but they do not replace batch-specific testing or a review of the supplier’s certificate of analysis.
Before requesting a quotation, I suggest defining whether you need material for early route scouting, process development, scale-up studies, or routine manufacturing. A research team may prioritize small-pack availability and fast technical communication, while a production buyer may require consistent lots, formal change notification, export documentation, and a more structured supply plan. The best supplier is therefore the one that matches both the chemical requirement and the project stage.
Ask the supplier to confirm the product name, CAS number, molecular formula, molecular weight, physical form, and any relevant storage information. I would also request the current product specification and a representative or batch-specific certificate of analysis before placing a larger order. If the material is intended for a demanding coupling sequence, the documentation should make clear which tests are performed and which results are reported for the supplied lot.
A useful certificate of analysis should identify the batch or lot number and include the test date or release information. Depending on the supplier’s quality system and product specification, it may report assay, appearance, identification, water or moisture, residual solvents, and other relevant impurity controls. Buyers should not assume that a general product page represents the exact quality of every shipment; the lot-specific document is more useful for release decisions.
Pay attention to how purity is defined. An assay reported as a percentage may be determined by different analytical methods, and chromatographic purity is not always identical to assay on an absolute basis. I recommend asking which method is used, whether the result is typical or guaranteed, and whether the supplier can discuss an observed impurity that could affect your reaction.
In Suzuki coupling, the boronic acid is normally used with an aryl or vinyl halide, a palladium catalyst or related catalytic system, and a suitable base and solvent system. Reaction performance can be influenced by substrate structure, water content, catalyst selection, base, temperature, reaction time, and the stability of the boronic acid under the chosen conditions. For that reason, a supplier should provide reliable product information without promising a reaction outcome that has not been demonstrated under your exact conditions.
For an early feasibility experiment, I would typically evaluate the supplier’s material at a small research scale, such as 0.1–1.0 mmol, using your established analytical method. This is not a universal recommended procedure; it is a practical way to compare conversion, selectivity, and handling before committing to a larger purchase. Your chemists should determine the actual equivalents, catalyst loading, base, solvent, temperature, and work-up based on the target reaction.
These questions help separate a documented chemical supply program from a listing that contains only a product name and CAS number. They also reduce the risk of discovering after delivery that the available grade, packaging, or documentation does not fit your internal release process.
Price is important, but it should be evaluated together with minimum order quantity, available inventory, production status, lead time, packaging, and shipping destination. A low unit price may not be advantageous if the supplier cannot provide the required quantity or if documentation must be recreated after the purchase. I recommend requesting a written quotation that separates product cost, packaging, freight, and any applicable export or handling charges.
With competitive price and timely delivery, Maison Chemical sincerely hope to be your supplier and partner.
For R&D, a small package can reduce inventory exposure and allow the chemistry team to qualify the material before a larger commitment. For process development, buyers may need larger packaging, lot consistency, and a realistic replenishment plan. Ask whether the quoted quantity is available now, made to order, or subject to an external production schedule.
Lead time should be stated as an estimate with clear assumptions, because production, quality release, customs, and transportation can affect the final delivery date. I would also confirm whether the supplier can reserve a later lot or support scheduled shipments. For international procurement, verify the shipping documents, outer packaging, label information, and destination-country requirements before dispatch.
A suitable B2B supplier should respond accurately to technical and commercial questions. The response does not need to include unsupported claims; it should clearly state what is confirmed, what is typical, and what must be checked against the specific batch. This distinction is especially important when a buyer is comparing purity, analytical methods, delivery estimates, or custom documentation.
At Maison Chemical, we support buyers by discussing product identity, specification requirements, packaging expectations, quotation details, and shipment planning for 3,4-Dichlorophenylboronic acid CAS 151169-75-4. We can review the intended use and help identify which documents should be requested for your internal evaluation. Product availability, batch information, commercial terms, and lead time should be confirmed directly for each inquiry rather than assumed from a general page.
One common mistake is selecting only by advertised purity without checking the test method, lot number, or actual COA. Another is assuming that a supplier’s stock status guarantees delivery to your destination, even though quality release and customs requirements may still apply. Buyers should also avoid treating a successful reaction in one laboratory as proof that the material will perform identically in every solvent, catalyst system, or scale.
A further mistake is ordering too much material before confirming application fit. If the project is still at route-screening stage, a smaller qualification order may provide better control of cost and inventory. Conversely, if a process is moving toward repeated production, the buyer should discuss supply continuity before the existing lot is nearly exhausted.
I suggest using a weighted comparison rather than choosing the lowest quotation. Identity and documentation should be treated as essential requirements, while price, MOQ, lead time, packaging, and communication can be compared after those requirements are met. A supplier that provides clear batch evidence and realistic delivery information may reduce the total sourcing risk even when its initial unit price is not the lowest.
For Suzuki coupling and R&D, the preferred supplier should be able to support a controlled qualification process: review the product information, receive an appropriate sample or package, test the material within your own method, and then establish a repeat-order plan if the results are acceptable. This approach creates a practical link between chemical quality and project execution without relying on unsupported performance guarantees.
The right 3,4-Dichlorophenylboronic acid CAS 151169-75-4 supplier is not simply the one offering the lowest price. It is the supplier that can verify product identity, provide suitable quality documentation, communicate realistic supply conditions, and support your transition from R&D screening to repeat procurement. These factors are particularly relevant when the material will be evaluated in Suzuki coupling, where the reaction result depends on the complete experimental system as well as the starting material.
