I use this guide to help research, process-development, and purchasing teams evaluate and source 3,5-Dichlorophenylboronic acid with CAS 67492-50-6. The material is an aromatic boronic acid used primarily as a boron-containing building block in synthetic chemistry, especially in palladium-catalyzed cross-coupling workflows. For procurement, the most important checks are identity, assay, impurity profile, packaging, documentation, and the supplier’s ability to provide a consistent lot. Maison Chemical supplies this product for B2B applications and can review quantity, specification, and delivery requirements before quotation.
This guide is intended for pharmaceutical and agrochemical research teams, fine chemical manufacturers, contract research organizations, process-development laboratories, and distributors of organic intermediates. It is also relevant to buyers who need to compare catalog material with a more structured commercial supply arrangement. I focus on procurement decisions rather than presenting the compound as a finished active ingredient or a ready-to-use formulation.
Buyers should distinguish between an early-stage laboratory purchase and a repeat manufacturing requirement. A small research order may prioritize availability and a suitable analytical certificate, while a production-oriented project may require lot-to-lot consistency, controlled packaging, defined release testing, and a documented supply plan. These requirements should be communicated before the quotation stage.
3,5-Dichlorophenylboronic acid is an organoboronic acid containing a phenyl ring substituted with chlorine atoms at the 3 and 5 positions and a boronic acid group. The CAS number is 67492-50-6, which should be used together with the chemical name during supplier communication to reduce the risk of selecting a positional isomer. The molecular formula is commonly represented as C6H5BCl2O2, with a calculated molecular weight of approximately 190.82 g/mol.
Its boronic acid functionality makes it relevant to carbon-carbon bond-forming chemistry, including Suzuki-Miyaura-type coupling reactions. The actual suitability of the material depends on the reaction system, catalyst, base, solvent, temperature, substrate, and downstream purification strategy. I therefore recommend treating the product as a synthetic intermediate and validating it within the buyer’s own process rather than assuming identical performance in every application.
The first specification layer should confirm the product name, CAS number, molecular formula, and expected molecular weight. Buyers may also request appearance, storage recommendation, packaging format, and a current certificate of analysis. Because physical descriptions can vary with particle size, handling, and storage history, I recommend using the supplier’s approved specification rather than relying only on a generic catalog description.
| Procurement item | What I recommend checking |
|---|---|
| Identity | 3,5-Dichlorophenylboronic acid and CAS 67492-50-6 match across quotation, label, and documents |
| Assay | Buyer-defined minimum value and the analytical method used for release |
| Impurities | Residual starting materials, positional isomers, inorganic residues, and process-related impurities where relevant |
| Packaging | Container material, net weight, sealing, labeling, and protection from unsuitable storage conditions |
| Documents | Certificate of analysis, safety data sheet, specification sheet, and shipping documents as applicable |
A target assay should not be selected only because it appears on a website. I suggest asking whether the stated value is a release specification, a typical result, or a single historical test result. If the compound will enter a regulated or tightly controlled process, buyers should also define whether chromatographic purity, water content, residual solvents, elemental impurities, or other tests are necessary.
For medicinal chemistry and discovery research, the buyer may need a small quantity with reliable identity confirmation and fast documentation. In this setting, a practical purchase decision often balances available stock, package size, assay, and the need for repeat ordering. The material should still be handled according to its safety documentation and the laboratory’s chemical-management procedures.
For process development, the specification must be more closely connected to reaction performance and purification. The development team may need information about impurity patterns, water content, residual solvents, and batch history because these factors can influence reproducibility. I recommend obtaining a representative sample or technical review before committing to a larger volume when the compound is a critical reaction input.
For commercial or scale-up procurement, continuity becomes as important as unit price. Buyers should ask how the supplier manages production scheduling, batch allocation, packaging changes, and forecast updates. A commercially useful quotation should clarify whether the quoted quantity is available from stock, made to order, or subject to a production campaign.
Start by stating whether the material is for route scouting, analytical research, process development, registration support, or routine manufacturing. The intended use determines the level of documentation and testing that should be requested. It also helps the supplier recommend a suitable package size and avoid quoting an unsuitable grade.
Prepare a short specification covering identity, assay, appearance, impurity limits, packaging, storage, and required documents. If some tests are not required, state that clearly rather than leaving the supplier to make assumptions. For repeat supply, include acceptance criteria for future lots and define how deviations will be reviewed.

Request a quotation that identifies price basis, available quantity, MOQ, lead time, packing, payment terms, and shipping terms. MOQ and lead time are not fixed universal properties of this chemical; they depend on inventory, production planning, order size, destination, and the agreed specification. Maison Chemical can assess these points after receiving the buyer’s quantity and delivery information.
Before purchase, compare the quotation, label information, certificate of analysis, and safety data sheet. The CAS number should be consistent throughout the document set, and the test results should correspond to the lot being supplied. If the buyer requires a particular analytical method, that request should be confirmed in writing before order acceptance.
The price of 3,5-Dichlorophenylboronic acid is influenced by quantity, purity requirement, packaging, production route, testing scope, and shipping destination. A low unit price may not represent the lowest total procurement cost if it comes with a large MOQ, extended lead time, or insufficient documentation. I recommend comparing complete delivered requirements rather than comparing only the price per gram or kilogram.
For planning purposes, buyers should provide an estimated annual demand, preferred shipment size, first required delivery date, and expected reorder frequency. An initial order and a repeat order may have different commercial conditions because stock status and manufacturing allocation can change. If the project has a fixed campaign date, I suggest requesting a written lead-time estimate and confirming it again before purchase order release.
Supplier responsiveness is also a practical evaluation factor. A capable B2B supplier should be able to clarify what is confirmed, what is estimated, and what requires technical approval. I recommend treating precise communication as part of supply quality, while avoiding unsupported assumptions about certifications, production scale, or regulatory status unless the supplier provides relevant documentation.
One common mistake is ordering by a shortened name without verifying the CAS number and substitution pattern. Another is specifying only “high purity” without defining the analytical method, minimum assay, or critical impurities. Buyers can also create avoidable delays by requesting a quotation without stating quantity, destination, packaging preference, or required documents.
A further risk is treating a single successful laboratory experiment as proof that every future lot will perform identically. Reaction performance can be affected by the complete process, including catalyst quality, base, solvent, substrate, and work-up conditions. For critical applications, I recommend retaining representative samples, reviewing incoming-lot results, and discussing any observed variation with the supplier.
Maison Chemical supports B2B sourcing of 3,5-Dichlorophenylboronic acid CAS 67492-50-6 by coordinating product identification, specification review, packaging discussion, quotation, and shipment planning. We can review whether the buyer needs research quantities, larger project quantities, or a repeat-supply arrangement. Final availability, MOQ, lead time, and price should be confirmed against the actual order requirements.
When a buyer sends an inquiry, I recommend including the required quantity, target purity, application stage, destination country, preferred delivery date, and document requirements. This information allows us to provide a more relevant commercial response and identify questions before order confirmation. Where the application is sensitive to impurity or moisture levels, the requested control points should be stated at the beginning of the discussion.
The most reliable way to source 3,5-Dichlorophenylboronic acid CAS 67492-50-6 is to combine verified identity, application-appropriate specifications, lot-specific documentation, and clear commercial planning. A suitable supplier should be able to discuss assay, impurities, packaging, MOQ, lead time, and repeat-order expectations without making unsupported guarantees. Price matters, but it should be evaluated together with quality requirements and supply continuity.
To begin, send Maison Chemical your target quantity, required specification, destination, preferred delivery date, and documentation needs. We can then review the request and provide a quotation based on the actual procurement conditions. This structured approach helps buyers move from product identification to a practical and lower-risk purchasing decision.
