Used primarily in the synthesis of flavor and fragrance compounds due to its sulfur-containing structure, which contributes to aroma profiles in food additives and perfumery. It serves as an intermediate in organic synthesis, particularly in creating thioethers and disulfides with desirable olfactory properties. Also investigated for use in agrochemicals as a building block for sulfur-based active ingredients. Its strong, pungent odor limits direct application but makes it valuable in trace-level scent formulations.
