  • Applications

    5-Phenylpent-4-enal, CAS 36884-75-0, is primarily used as a fragrance-related intermediate and odorant in perfumery, contributing to aromatic notes and serving as a building block for other aroma compounds. It may also find use in cosmetics/personal care formulations as a fragrance ingredient. In industrial manufacturing, it is employed as a chemical intermediate for synthesis of aroma-related specialty chemicals. It can be explored as a precursor for aroma or flavor compounds in controlled formulations, and may appear in coatings and inks as part of fragrance additives, subject to regulatory compliance and formulation limits.
