2-Mercaptothiazole serves as a surface modifier for cathode materials and acts in the organocatalysis of C-H borylation[1]. 2-Mercaptothiazole is employed as an additive to refine copper grains during electrodeposition and to investigate the strength and mechanical properties of electrolytic copper foils[2].

2-Mercaptothiazole derivatives are obtained via modification of the sulfur atom or synthesized from thiocyanatoketones and thiourea in a mixture of concentrated hydrochloric acid and ethanol under reflux[1].
