Used primarily in the synthesis of organic compounds, particularly in the production of polymers and resins. It serves as a key intermediate in the manufacture of certain types of plastics and adhesives. Additionally, it is utilized in the flavor and fragrance industry to impart unique odors, often mimicking the smell of garlic or onion. In research, it is employed as a reagent for studying thiol-ene reactions, which are important in material science and biochemistry. Its strong, distinctive odor also makes it useful in leak detection for natural gas systems.
