2-Chloro-4-methylbenzoyl chloride

Description:
2-Chloro-4-methylbenzoyl chloride, with the CAS number 21900-53-8, is an organic compound characterized by its aromatic structure, which includes a benzoyl chloride functional group. This compound features a chlorine atom and a methyl group attached to the benzene ring, specifically at the 2 and 4 positions, respectively. It is typically a colorless to pale yellow liquid with a pungent odor, indicative of its reactivity. As an acyl chloride, it is highly reactive, particularly with nucleophiles, making it useful in various chemical synthesis processes, including the preparation of esters and amides. The presence of the chlorine atom enhances its electrophilic character, facilitating reactions with alcohols and amines. Due to its reactivity, 2-chloro-4-methylbenzoyl chloride must be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. It is also important to store it in a cool, dry place, away from moisture, to prevent hydrolysis and degradation.
