If I were evaluating 4-Isopropylbenzeneboronic acid CAS 16152-51-5 for a research, pharmaceutical, or specialty chemical project, I would first confirm identity, analytical requirements, packaging, and supply conditions before comparing price. This compound is an aromatic boronic acid used primarily as a building block in organic synthesis, including palladium-catalyzed cross-coupling workflows. Its commonly referenced molecular formula is C9H13BO2, with an approximate molecular weight of 164.01 g/mol. Maison Chemical can support buyers with product documentation, quotation review, packaging discussions, and shipment coordination based on the required grade and order quantity.
This guide is intended for procurement teams, process chemists, R&D laboratories, pharmaceutical intermediate developers, and distributors sourcing 4-Isopropylbenzeneboronic acid. It is especially useful when a buyer needs more than a catalog name and wants to review the practical details behind a purchase. These details include identification, purity targets, COA content, packaging, storage, MOQ, lead time, and export support. I recommend using this guide as a screening framework rather than treating it as a substitute for a product-specific quotation or batch COA.
4-Isopropylbenzeneboronic acid is an aryl boronic acid in which the boronic acid group and the isopropyl substituent occupy the para position on the benzene ring. The boronic acid functionality is valuable because it can participate in synthetic transformations, most notably Suzuki–Miyaura-type carbon–carbon coupling reactions under suitable conditions. The actual reaction performance, however, depends on the complete reaction system, including catalyst, base, solvent, temperature, substrate, and handling conditions.
The CAS number 16152-51-5 is an important purchasing identifier, but it should not be the only identity check. I advise buyers to compare the CAS number with the molecular formula, molecular weight, product name, structural representation, and supplier documentation. Where the material is intended for a regulated or tightly controlled development program, the internal specification should also define acceptable impurity and residual-solvent limits.
A commercial inquiry should clearly state the required purity and analytical basis. Common specification items may include appearance, assay or purity by HPLC, identity by NMR or another appropriate technique, water content, residual solvents, and inorganic or elemental impurities where relevant. Because specification formats vary by supplier and application, I recommend requesting the current product specification before placing an order rather than assuming that every supplier uses the same test method.
| Specification Area | What the Buyer Should Confirm |
|---|---|
| Identity | CAS 16152-51-5, chemical name, molecular formula, and suitable analytical identification |
| Purity | Target assay, test method, reporting basis, and impurity profile |
| Physical form | Expected appearance, lot-to-lot consistency, and any handling precautions |
| Moisture and solvents | Water content and residual-solvent limits relevant to the process |
| Documentation | COA, SDS, specification sheet, batch number, and manufacturing or retest information where available |
Some buyers may only need research-grade material for early screening, while others require tighter controls for route development or intermediate manufacturing. These are not interchangeable purchasing situations. A higher purity target can affect analytical testing, production planning, packaging, and price, so I recommend defining the intended use before requesting a quotation.
A Certificate of Analysis should connect the supplied material to a specific batch, not merely describe a generic product. I would check the product name, CAS number, batch or lot number, test date, release date, specification limits, actual results, analytical methods, and authorized approval. The COA should make it possible to understand what was tested and whether the reported result meets the stated specification.
A reported purity value should always be interpreted together with the method and specification. For example, an HPLC result expressed as an area percentage does not automatically describe every possible impurity or the total mass assay. If a process has sensitive downstream requirements, I suggest sharing the buyer’s analytical expectations with Maison Chemical before shipment so the documentation can be reviewed in advance.
For synthetic chemistry, the key question is whether the material is suitable for the planned transformation and workup. Buyers should consider the sensitivity of the reaction to moisture, trace metals, residual solvents, and boronic acid-related impurities. A material that is adequate for exploratory experiments may not be adequate for scale-up without additional qualification.
You will get efficient and thoughtful service from Maison Chemical.
For procurement, I recommend evaluating five factors: identity, purity, documentation, packaging, and continuity of supply. A lower unit price may not be the best commercial choice if the lot size, COA format, or delivery schedule does not fit the project. Conversely, an unnecessarily strict specification may increase cost without improving the intended process.
Packaging should be selected according to order quantity, frequency of use, transportation requirements, and the buyer’s storage system. Small quantities may be supplied in a sealed inner container suitable for laboratory handling, while larger orders may require a carefully selected outer package with appropriate labeling and protection. The final packaging configuration should be confirmed in the quotation because available pack sizes and materials can vary by order.
I advise buyers to store the product according to the supplier’s SDS and product-specific instructions. The container should remain properly closed, clearly labeled, and protected from conditions that may affect material quality. Storage temperature, light exposure, moisture control, and resealing practices should be reviewed by the receiving laboratory or warehouse rather than inferred from a general chemical category.
For international supply, the commercial discussion should also cover Incoterms, destination, shipping method, export documents, and any import requirements. The order quantity should be stated in kg or g, and the requested delivery window should be stated in calendar days or weeks. These details allow the supplier to assess production availability and provide a more realistic quotation.
MOQ and lead time are normally quotation-specific because they depend on stock status, batch availability, production scheduling, packaging, and destination. I do not recommend relying on an unqualified standard lead time. Instead, ask for the available quantity, expected dispatch timing, whether the material is from one batch, and whether a fresh production batch is required.
Maison Chemical approaches this product as a B2B supply project rather than only a catalog transaction. We can review the requested grade, quantity, destination, packaging preference, and documentation needs before preparing a quotation. Where the buyer has a defined internal specification, sharing it early can reduce clarification cycles and help align the supply plan.
The right way to buy 4-Isopropylbenzeneboronic acid CAS 16152-51-5 is to evaluate the complete supply package: chemical identity, specification, COA, packaging, logistics, and future availability. Start by defining the intended application, purity target, order quantity, destination, and documentation requirements. Then request a product-specific quotation and confirm that the proposed batch and packaging meet your internal approval process.
Maison Chemical can support your evaluation with a technical and commercial discussion tailored to your project. When sending an inquiry, include the required quantity, target purity, preferred packaging, delivery location, and any COA or SDS requirements. This gives our team the information needed to respond with a practical supply option for your 4-Isopropylbenzeneboronic acid procurement plan.
