Also known as CI-9148, cysteamine hydrochloride, L-1573, beta-aminoethylthiol, 2-amino-1-ethanethiol, MEA, beta-MEA, Cisteamina
Cysteamine is an organosulfur compound with the formula . A white, water-soluble solid, it contains both an amine and a thiol functional group. It is often used as the salt of the ammonium derivative [HSCH2CH2NH3]+, including the hydrochloride, and the bitartrate. Another derivative is phosphocysteamine, . The intermediate pantetheine is broken down into cysteamine and pantothenic acid.

The intermediate pantetheine is broken down into cysteamine and pantothenic acid.
It is biosynthesized in mammals, including humans, by the degradation of coenzyme A. It is the biosynthetic precursor to the neurotransmitter hypotaurine.
