  • Applications

    4-Undecanone (CAS 14476-37-0) is used as a fragrance ingredient and odorant in perfumery and cosmetics, contributing distinctive aliphatic notes to formulations. It is commonly evaluated as an intermediate in the synthesis of longer-chain fragrance molecules and may serve as a processing aid or solvent in industrial production. It also appears in household products as an odorant or fragrance component, helping to impart fresh, waxy, or clean notes. In industrial settings, it is employed as a building block in fragrance synthesis and related studies.
