For professionals in the chemical and pharmaceutical industries, a deep understanding of product specifications is non-negotiable when making purchasing decisions. Bis(4-methoxyphenyl)chlorophosphine (CAS 13685-30-8), a vital pharmaceutical intermediate, demands careful attention to its key parameters to ensure successful application in synthesis. This article outlines the essential specifications that R&D scientists and procurement managers should look for when they intend to buy this organophosphorus compound.

At the forefront of specifications is purity. Bis(4-methoxyphenyl)chlorophosphine is typically supplied with a minimum purity of 98%. This high level of purity is critical for its intended use as a pharmaceutical intermediate, where even trace impurities can impact reaction outcomes and the quality of the final product. Manufacturers, especially those in China, are often capable of achieving and verifying this purity through rigorous quality control measures. When you buy, always request a Certificate of Analysis (CoA) that clearly states the purity and any detected impurities.

Another crucial specification is the physical appearance. Bis(4-methoxyphenyl)chlorophosphine is commonly described as a white to off-white powder. Deviations from this description could indicate product degradation or contamination. Its solid form also implies specific handling and storage requirements, as it is noted to be moisture-sensitive. Suppliers who provide clear guidance on storage and handling, such as recommending storage away from air and moisture, demonstrate a commitment to product quality and customer support. For B2B buyers, this information is vital for maintaining the integrity of the purchased material.

Understanding the chemical properties, such as its molecular formula (C14H14ClO2P) and molecular weight (280.69 g/mol), is fundamental for chemists planning reaction stoichiometry and logistics. The boiling point (140°C at 1.5 mmHg) and melting point (61-64°C) provide insights into its stability and physical behavior under different conditions. These details are essential for researchers designing synthesis protocols and for procurement teams assessing the material's handling requirements during transportation and storage.
