Description

4-(Chloromethyl)benzoyl chloride (CAS No. 876-08-4) is a highly reactive organic compound with the molecular formula C₈H₆Cl₂O. This aromatic acyl chloride features both a chloromethyl (-CH₂Cl) and a benzoyl chloride (-COCl) functional group, making it a versatile intermediate for synthetic organic chemistry applications. The compound appears as a colorless to pale yellow liquid with a pungent odor and should be handled with care due to its moisture sensitivity and corrosive nature. It is commonly used in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. Store under inert conditions (argon or nitrogen) in a cool, dry place to prevent hydrolysis. Purity levels typically exceed 98% (GC), with technical grades also available for industrial applications.
