ClCHCOCl

ClCHCOCl, also known as chloroacetyl chloride, is an organic compound with the chemical formula ClCH2COCl. It is a colorless to pale yellow liquid with a pungent odor. Chloroacetyl chloride is an acyl chloride and a derivative of acetic acid. Its structure features a carbonyl group bonded to a chlorine atom and a chloromethyl group.

This compound is highly reactive due to the presence of the acyl chloride functional group, making it susceptible to nucleophilic attack. It reacts readily with water to form chloroacetic acid and hydrochloric acid, and with alcohols to form chloroacetates. Chloroacetyl chloride is an important intermediate in organic synthesis. It is used in the production of pharmaceuticals, agrochemicals, and dyes. For example, it is a precursor in the synthesis of certain herbicides and pharmaceuticals containing the chloroacetyl moiety. Due to its reactivity and corrosive nature, it must be handled with care in well-ventilated areas, wearing appropriate protective equipment.
