  • Applications

    1-Phenyl-2-pentanol (CAS 705-73-7) is primarily employed as an intermediate in fragrance chemistry and can act as an odorant or fragrance ingredient in perfumery and cosmetics/personal care. It is sometimes used in household and cleaning formulations as a fragrance additive, contributing to the overall aroma profile. In industrial manufacturing, it serves as a building block for synthesizing other aroma compounds. In coatings, inks, and related applications, it may be used as a fragrance modifier to impart a targeted scent. Use is subject to local regulations and formulation limits.
