Acetyl Chloride is a colorless liquid with a pungent odor, commonly used in organic chemistry. It is an acyl chloride derived from acetic acid and is known for its ability to react with alcohols and amines to form esters and amides, respectively. This makes it a valuable reagent in the synthesis of various chemical compounds. Due to its reactivity, acetyl chloride must be handled with care, as it can cause burns and is corrosive to skin and eyes. It is typically stored in tightly sealed containers to prevent moisture absorption, which can lead to hydrolysis and the formation of acetic acid.
