Cysteamine is the chemical compound with the formula HSCH2CH2NH2. Cysteamine hydrochloride is used as an antioxidant and in radiation therapy. 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℃), indicates that it exists in a salt form.
