Acetyl chloride (Cat No.:R023696) is a colorless, highly reactive liquid with a pungent odor, widely used as an acylating agent in organic synthesis. It is commonly employed to introduce acetyl groups into alcohols, amines, and other nucleophilic substrates, forming esters and amides. Acetyl chloride reacts violently with water, releasing corrosive hydrogen chloride gas, and must be handled under anhydrous conditions. It plays a key role in pharmaceutical, agrochemical, and dye manufacturing. Due to its corrosiveness and volatility, proper protective equipment and fume hood use are essential during handling.
