  • Applications

    Chemical name: 3-((2,5-Dihydro-2-methyl-3-furyl)thio)tetrahydro-2-methylfuran-3-thiol; CAS 38325-24-5. This sulfur-containing compound is primarily discussed as an odorant/fragrance ingredient, commonly evaluated for use in perfumery and personal care products, and may also serve as a scent modifier or fixative in household cleaners. It can function as an intermediate in the synthesis of specialized fragrance chemicals for the industrial manufacturing of aroma compounds, and its thiol functionality may enable further chemical transformations useful in specialty polymers or coatings applications. Any actual use would be subject to local regulations and formulation limits.
