Cystamine (2,2'-dithiobisethanamine) is an organic disulfide. It is formed when cystine is heated, the result of decarboxylation. Cystamine is an unstable liquid and is generally handled as the dihydrochloride salt, C4H12N2S2·2HCl, which is stable to 203-214 °C at which point it decomposes. Cystamine is toxic if swallowed[citation needed] or inhaled and potentially harmful by contact.
