It is a colorless liquid that is used to attach the valeroyl group.

It is usually produced by chlorination of valeric acid.

[1] Like related acyl chlorides, valeryl chloride hydrolyzes readily: Alcohols react to give esters: Amines react to give amides: Benzene reacts under conditions of the Friedel-Crafts reaction to give valerophenone: This article about an organic halide is a stub.
