Butyryl Chloride, or Butanoyl Chloride (CAS 141-75-3), is a highly reactive organic compound that plays a significant role as an acylating agent across various industrial sectors. As a chemical manufacturer focused on delivering essential raw materials, we understand the importance of detailing the chemical profile of such compounds for our B2B clients. If you are considering purchasing Butyryl Chloride, familiarizing yourself with its properties is key to its effective utilization.

Chemically, Butyryl Chloride is an acyl chloride with the formula CH3CH2CH2COCl. It typically presents as a colorless liquid with a pungent, irritating odor, characteristic of many acyl chlorides. Its high reactivity stems from the polarized carbon-chlorine bond and the electron-withdrawing effect of the carbonyl group. This makes it readily susceptible to nucleophilic attack, a property that underpins its utility in synthesis.

A crucial aspect of Butyryl Chloride's chemical behavior is its reaction with water, where it undergoes rapid hydrolysis to form butanoic acid and hydrochloric acid. This reactivity necessitates careful handling, storage in sealed containers, and protection from moisture. Similarly, it reacts vigorously with alcohols to form esters and with amines to form amides. These reactions are precisely what make it valuable for introducing the butyryl moiety into other molecules.

The industrial applications of Butyryl Chloride are extensive. In the agrochemical industry, it is a critical intermediate for synthesizing a range of pesticides, including specific herbicides and insecticides. Its role in creating molecules like fenoxaprop-p-ethyl demonstrates its importance in modern crop protection. For farmers and agricultural chemical producers, securing a reliable supply of high-purity Butyryl Chloride ensures the efficacy of their end products.

In the pharmaceutical sector, Butyryl Chloride acts as a versatile intermediate for the synthesis of active pharmaceutical ingredients (APIs). Its ability to participate in acylation reactions is fundamental to building the complex structures of many drugs. The demand for high-purity Butyryl Chloride in this industry underscores the need for stringent quality control from chemical manufacturers and suppliers.

Beyond these core areas, Butyryl Chloride also finds use in the production of specialty chemicals, flavoring agents, and fragrances, where the butyryl group contributes specific aromatic or functional properties. Researchers and production managers looking to buy this chemical often prioritize consistency in its physical and chemical properties, such as its boiling point (around 102°C) and density (approximately 1.033 g/cm³).

For any organization in need of Butyryl Chloride, partnering with a reputable chemical supplier is essential. Access to detailed technical specifications, a commitment to product quality, and competitive pricing for bulk orders are key factors. Understanding the chemical profile of Butyryl Chloride empowers users to leverage its reactivity safely and effectively, driving innovation and efficiency in their respective industries.
