Used as a corrosion inhibitor for metals, particularly in acidic environments. It is effective in protecting steel and copper alloys by forming a protective film on the metal surface, reducing oxidation and degradation. Also employed in electroplating processes to improve deposit quality and uniformity. Additionally, serves as an intermediate in synthesizing pharmaceuticals and agrochemicals due to its reactive thiol and imidazole groups. Its derivatives show potential in antimicrobial and antifungal applications.
