  • Applications

    2-Octen-1-ol, 3,7-dimethyl- (CAS 40607-48-5) is primarily used as a fragrance ingredient and odorant in perfumery, and as a chemical intermediate for the synthesis of related terpenoid aroma compounds. It may function as a fixative in fragrance formulations and is considered for use in cosmetics/personal care to enhance fragrance delivery. In household products, it can be added as a fragrance component to impart or stabilize scent. As an industrial intermediate, it supports the production of related aroma compounds and other specialty chemicals. It may also be evaluated for flavor/aroma applications in food processing or as a building block for related industries, subject to regulatory constraints and formulation limits.
