  • Applications

    2,7-Octadien-1-ol (CAS 23578-51-0) is a long-chain unsaturated alcohol with two double bonds, regarded as a precursor and fragrance component in perfumery and cosmetics; it is commonly evaluated for use as an intermediate or odorant in fragrance formulations and personal care products; it may be converted into aromatic esters for flavors and cosmetic applications; it is also considered an industrial building block for fragrance-related compounds and other specialty chemicals; it can serve as a precursor for polymer or materials-related syntheses via functionalization of its unsaturation; its use is subject to local regulations and formulation limits.
