Butyryl chloride

Butyryl chloride is an organic compound with the chemical formula CH3CH2CH2C(O)Cl.

Butyryl chloride is soluble in organic solvents, but it reacts readily with water and alcohols.

It is usually produced by chlorination of butyric acid.

[1] Like related acyl chlorides, butyryl chloride hydrolyzes readily: Alcohols react to give esters: Amines react to give amides: Derivatives of butyryl chloride are used in manufacturing pesticides, pharmaceuticals, perfume fixative, polymerization catalyst, and dyestuffs.

Butyryl chloride is also commonly used as an intermediate for organic synthesis for the preparation of pharmaceuticals, agrochemicals, dyes, esters, and peroxide compounds.
