  • Applications

    1-p-MENTHENE-8-THIOL (CAS 71159-90-5) is primarily encountered as an aroma-related compound and may be used in perfumery and fragrance applications as an odorant and potential fixative. It may also function as an aroma chemical for flavor formulations, subject to regulatory compliance. In cosmetics and personal care, it can be used as a fragrance ingredient. In household products, it may serve as a scent additive in cleaners and air fresheners. In industrial manufacturing, it can be employed as an intermediate in fragrance synthesis and in coatings, inks, or polymers where odor control or scent is desired. In research and development, it is commonly evaluated for formulation profiling and sensory characterization.
