Used primarily in the flavor and fragrance industry to impart fruity, tropical, or sulfury notes in food products, beverages, and perfumes. It serves as a key ingredient in creating artificial flavors, particularly for pineapple, passion fruit, and other exotic fruits. Additionally, it acts as a precursor in organic synthesis for producing sulfur-containing compounds. Its unique thiol group makes it valuable in polymer chemistry for modifying or cross-linking polymers. In some cases, it is also used as a stabilizer or antioxidant in certain industrial applications.
