2-Aminothiazoline-4-carboxylic acid (ACTA) is the organosulfur compound and a heterocycle with the formula HO2CCHCH2SCNH2N. This derivative of thiazoline is an intermediate in the industrial synthesis of L- cysteine, an amino acid. ACTA exists in equilibrium with its tautomer 2-iminothiazolidine-4-carboxylic acid.
It is produced by the reaction of methyl chloroacrylate with thiourea. [1] It is also a biomarker for cyanide poisoning, as it results from the condensation of cysteine and cyanide. [2]
