Description and Uses

2-AMINOETHANETHIOL is the chemical compound with the formula HSCH₂CH₂NH₂. It is the simplest stable aminothiol and a degradation product of the amino acid cysteine. It is often used as the hydrochloride salt, HSCH₂CH₂NH₃Cl. The comparatively high melting point of cysteamine (95-97 °C), indicates that exists in a salt form.

antihyperlipidemic, HMGCoA reductase inhibitor
