For procurement specialists and R&D scientists, identifying reliable sources for specialized chemical intermediates is a critical task. 3-Chlorophenylboronic acid pinacol ester, known by its CAS number 635305-47-4, is a highly sought-after building block in organic synthesis, particularly for its role in Suzuki-Miyaura cross-coupling reactions. This guide aims to assist buyers in understanding what to look for when sourcing this essential compound, especially from manufacturers in China.

The primary consideration when purchasing 3-Chlorophenylboronic acid pinacol ester is its purity. High purity is essential for ensuring consistent reaction outcomes, minimizing by-products, and achieving desired yields in complex syntheses. Look for suppliers who clearly state the purity level, typically 95% or higher for this specific intermediate, and ideally provide certificates of analysis (CoA) detailing key specifications such as NMR data, GC or HPLC purity, and moisture content. As a dedicated manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. places a strong emphasis on purity and provides comprehensive documentation for our CAS 635305-47-4 product.

Beyond purity, consider the supplier's reliability and capacity. Can they consistently supply the quantities you need, whether for R&D or larger-scale production? A supplier with a proven track record in export and robust quality control measures is invaluable. Understanding their manufacturing capabilities and logistical support will streamline your procurement process. When you choose to buy from our company, you are assured of a stable supply chain and efficient delivery, backed by our expertise as a leading chemical supplier.

The chemical structure itself, 3-Chlorophenylboronic acid pinacol ester, lends itself to various applications, primarily in the synthesis of pharmaceuticals, agrochemicals, and advanced materials. Its stability, due to the pinacol ester group, makes it a preferred choice over free boronic acids in many synthetic protocols. The presence of the chlorine atom offers a handle for further functionalization or influences the electronic properties of the final molecule.

When evaluating potential suppliers, inquire about their expertise in handling and packaging sensitive chemical compounds. Proper packaging under inert atmosphere and protection from moisture are crucial for maintaining the integrity of boronate esters. For companies looking to purchase CAS 635305-47-4, engaging with manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. offers direct access to product expertise, competitive pricing, and a commitment to customer satisfaction. Our goal is to be your trusted partner in sourcing high-quality chemical intermediates.
