  • Applications

    3-Mercapto-3-methylhexan-1-ol (CAS 307964-23-4) is a sulfur-containing alcohol used as a specialized building block in fragrance chemistry and related industrial synthesis. In perfumery, it functions as an odorant and a precursor to sulfur-containing aroma compounds; in cosmetics and personal care, it is commonly evaluated as a fragrance intermediate and a reactive handle for downstream sulfur-containing additives. In industrial manufacturing and polymer-related applications, it may be used as an intermediate for sulfur-containing compounds and as a thiol-functional reagent suitable for thiol-ene and related crosslinking chemistries in coatings, adhesives, and plastics. Overall, its use is formulation- and regulation-dependent, and companies typically assess it for specific fragrance, polymer, or coating applications within local guidelines.
