  • Applications

    1-(5-Ethylfuran-2-yl)ethan-1-one (CAS 24119-98-0) is primarily used as a fragrance intermediate and odorant in perfumery, contributing furanyl notes to scent profiles. In cosmetics and personal care formulations, it is evaluated as a fragrance ingredient and aroma precursor. In household products, it can serve as a scent additive to impart specific odor characteristics. In industrial manufacturing and materials development, it is used as a chemical intermediate for the synthesis of fragrance-related monomers and specialty additives for polymers, coatings, and inks. In coatings and inks, it may function as a fragrance additive or aroma-delivery component within compatible formulations. Subject to local regulations and formulation limits.
