(2-Carbamimidamido-1,3-thiazol-4-yl)methyl carbamimidothioate dihydrochloride

It also serves as a pharmaceutical reference standard, notably as an impurity marker for the anti-ulcer drug Famotidine, helping ensure drug purity and quality in analytical testing. (2-Carbamimidamido-1,3-thiazol-4-yl)methyl carbamimidothioate dihydrochloride is mainly used in scientific research, especially as an intermediate for synthesizing other complex organic molecules, particularly in medicinal chemistry, due to its reactive guanidine and thiourea groups.
