pentanediamine

Pentanediamine, also known as pentamethylenediamine or cadaverine, is an organic compound with the chemical formula C5H14N2. It is a diamine, meaning it contains two amine functional groups. Pentanediamine is a colorless liquid at room temperature with a characteristic strong, unpleasant odor, which is often associated with the putrefaction of animal tissue, hence its common name derived from the Latin word for corpse.

This compound is produced naturally by the decarboxylation of the amino acid lysine during the breakdown of proteins by microorganisms. This process occurs post-mortem, contributing to the smell of decaying flesh. Industrially, pentanediamine can be synthesized through various chemical routes, including the hydrogenation of glutaronitrile.

Pentanediamine has found some applications in the chemical industry. It can be used as a monomer in the production of certain polyamides, which are types of plastics and synthetic fibers. It is also used as a cross-linking agent in some polymer formulations. Despite its potential industrial uses, its strong odor and association with decomposition limit its widespread application in consumer products. It is also a component in some biological studies related to protein metabolism and bacterial activity.
