For professionals in the pharmaceutical and chemical industries, the reliable sourcing of high-quality intermediates is paramount. One such critical compound is 4-(chloromethyl)benzoyl chloride, identified by CAS number 876-08-4. This versatile chemical intermediate serves as a fundamental building block in a wide array of synthetic organic chemistry applications, particularly within the pharmaceutical sector. Understanding its properties and reliable sourcing channels is key to efficient drug development and manufacturing.

4-(Chloromethyl)benzoyl chloride, with the molecular formula C8H6Cl2O and a molecular weight of approximately 189.04 g/mol, is characterized by its highly reactive nature. Typically appearing as a white to off-white solid, it possesses both a chloromethyl (-CH2Cl) and a benzoyl chloride (-COCl) functional group. These functionalities make it an invaluable reagent for introducing specific chemical structures into target molecules. Its melting point generally falls between 29-33°C, and its boiling point is around 126-128°C at 6 mmHg, indicating its utility in reactions requiring controlled conditions.

The primary utility of 4-(chloromethyl)benzoyl chloride lies in its role as a pharmaceutical intermediate. It is instrumental in the synthesis of Active Pharmaceutical Ingredients (APIs), prodrugs, and various complex organic molecules that form the basis of modern medicines. Beyond pharmaceuticals, this compound also finds significant application in the agrochemical industry for the production of crop protection agents and in the synthesis of specialty polymers, dyes, and photoinitiators. Its adaptability underscores its importance across multiple chemical manufacturing verticals.

When considering the purchase of 4-(chloromethyl)benzoyl chloride, it is crucial to engage with reputable manufacturers and suppliers. Companies specializing in chemical intermediates, especially those based in China, often provide competitive pricing and a commitment to product quality. For businesses looking to buy this essential chemical, seeking out suppliers that offer clear specifications, consistent purity (often exceeding 99% by GC), and secure packaging is advisable. Establishing a relationship with a dependable manufacturer ensures a stable supply chain, which is critical for uninterrupted production schedules.

Moreover, understanding the safe handling and storage of 4-(chloromethyl)benzoyl chloride is vital. Due to its reactive nature, it is sensitive to moisture and can be corrosive. Proper storage under inert conditions, in a cool, dry place, is recommended to maintain its integrity. For those in the market to purchase this compound, exploring options from established chemical suppliers will not only provide access to quality materials but also offer the technical support and documentation necessary for compliance and effective utilization. Engaging with a trusted chemical supplier means ensuring you receive not just a product, but a reliable partnership for your chemical sourcing needs.
