  • Applications

    (2S,3R)-2-methyltetrahydrofuran-3-thiol (CAS 26548-78-7) is primarily used as a synthetic building block in organic chemistry, serving as an intermediate for sulfur-containing heterocycles and other advanced intermediates in pharmaceuticals and agrochemicals. In addition, it may be used as an odorant or fragrance modifier in perfumery, leveraging its sulfur-containing notes. It can participate in thiol-ene chemistry for coatings, inks, and adhesives, acting as a reactive thiol partner for UV-curable formulations or crosslinking. It is also valued as a precursor for specialized sulfur-containing polymers and materials. All uses are subject to local regulations and formulation limits.
