  • Applications

    10-Undecenal, 2-ethylidene- is a long-chain aldehyde that is typically used in fragrance chemistry as an aroma ingredient and odorant, and may function as a fixative in some perfume formulations. It is commonly evaluated for cosmetic and personal care applications as a fragrance ingredient. In household products, it may be added as a fragrance additive in air fresheners, cleaners, and detergents. It may be evaluated for flavor applications as a cautious aroma precursor in certain food formulations. In industrial manufacturing, it can serve as a chemical intermediate for the synthesis of fragrance-related compounds or other specialty chemicals.
