Used as a preservative and antimicrobial agent in cosmetics and personal care products, particularly as an anti-dandruff ingredient in shampoos to inhibit fungal growth (e.g., Malassezia) on the scalp. It prevents the growth of bacteria and fungi in formulations like conditioners and lotions, extending shelf life. Also functions as a corrosion inhibitor in industrial water systems and metalworking fluids. In research, it serves as a ligand or reagent in organic synthesis due to its sulfur and nitrogen donor properties. This is a specialty chemical, functioning as a niche antimicrobial additive and intermediate.
