Common Name5-Phenylvaleric acid
Description5-Phenylvaleric acid, also known as delta-phenylvalerate or benzenepentanoic-acid, is a monocarboxylic acid that is valeric acid substituted by a phenyl group at the delta-position. It is a monocarboxylic acid and a member of benzenes. It derives from a valeric acid. 5-Phenylvaleric acid belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms.
