Used as a corrosion inhibitor in cooling water systems and industrial metal treatment, protecting copper and its alloys from oxidation and degradation. Acts as a key intermediate in synthesizing pharmaceuticals, including antiviral and antifungal agents. Employed in the development of coordination compounds with transition metals for catalytic applications. Applied in surface modification of nanoparticles, especially silver and gold, to enhance stability and functionalization for use in sensors and biomedical devices. Also utilized in the synthesis of agrochemicals and dyes due to its reactive thiol and heterocyclic structure.
