  • Applications

    p-Coumaric acid (CAS 7400-08-0) is commonly used as a building block in the synthesis of flavor and fragrance compounds for perfumery and taste applications; in cosmetics and personal care, it is evaluated as an antioxidant and a precursor for fragrance ingredients; in polymers and coatings, it serves as an antioxidant/stabilizer and as a feedstock for cinnamic acid derivatives; in industrial manufacturing, it functions as an intermediate for organic synthesis of related aromatic compounds; and in formulations with UV or photostability considerations, its phenolic structure is studied as a potential UV-absorbing additive. All uses depend on local regulations and formulation limits.
