  • Applications

    4-Pentadecanone (CAS 925-51-9) is primarily used as an odorant and perfumery fixative in fragrance and cosmetic applications, helping to extend fragrance longevity in personal care products. It may also function as a solvent or processing intermediate in industrial formulations and can be used as a component in plastics, coatings, and inks as a processing aid or modifier. Additionally, it can appear in household cleaning products as a fragrance ingredient, and may be evaluated for use as a fragrance system modifier in complex formulations, subject to local regulations and formulation limits.
