CH2ClCN

Chloroacetonitrile, also known by its chemical formula CH2ClCN, is an organic compound. It is a colorless liquid with a pungent odor. The molecule consists of an acetonitrile group (-CN) where one hydrogen atom on the methyl group has been replaced by a chlorine atom (-Cl). This makes it a halogenated nitrile.

Chloroacetonitrile is soluble in water and many organic solvents. Its properties are influenced by both the polar nitrile group and the electronegative chlorine atom. It can undergo various chemical reactions characteristic of nitriles and alkyl halides.

Industrially, chloroacetonitrile can be synthesized through several methods, often involving the chlorination of acetonitrile or related compounds. It finds application as an intermediate in the synthesis of various organic chemicals, including pharmaceuticals, pesticides, and dyes. Due to its reactivity, it is handled with care. It is considered toxic and an irritant.
