  • Applications

    epsilon-Fenchene (CAS 512-50-5) is primarily used in the fragrance sector as an odorant and fragrance ingredient, contributing to a range of perfume formulations; it is commonly evaluated as an intermediate in fragrance chemistry for the synthesis of aroma compounds; in cosmetics and personal care formulations it serves as a scent component; in household products it is used to impart fragrance in cleaners and laundry products; in industrial manufacturing it can function as a building block for aroma-related specialty chemicals and as a starting material in the synthesis of related fragrance compounds; its use is formulation- and regulation-dependent.
