Used as a corrosion inhibitor in industrial cooling systems and metalworking fluids, particularly effective in protecting copper and its alloys from oxidative degradation. Also serves as an intermediate in the synthesis of agrochemicals and pharmaceuticals due to its sulfur- and nitrogen-containing heterocyclic structure. Exhibits biocidal properties, making it useful in water treatment formulations to control microbial growth. Its derivatives are explored for potential antifungal and antibacterial applications in medicinal chemistry.
