  • Applications

    4,8-Dimethylnon-7-en-2-ol (CAS 40596-76-7) is typically encountered as an odorant and intermediate in fragrance chemistry. In perfumery and cosmetics, it may be used as a fragrance ingredient or as a building block to craft specific notes, and it can act as a potential fixative to influence volatility. In household products, it can serve as a scent additive for air fresheners and cleaners. In food processing, it may be evaluated as a flavor/aroma intermediate. In industrial manufacturing, it can function as a chemical intermediate for the synthesis of more complex terpenoid or fragrance compounds. Its use is subject to local regulations and formulation limits.
