  • Applications

    2-Methyl-2-tetrahydrothiophenethiol (CAS number: 62308-60-5) is used as an odorant and fragrance intermediate in perfumery and cosmetics, may serve as a scent component in household products, and can function as a reactive thiol in polymer and coating chemistries (enabling thiol-ene crosslinking and related bonding steps). It may also act as a curing or linking component in adhesives, and is often evaluated as an intermediate in industrial synthesis for building sulfur-containing heterocycles.
