  • Applications

    2-Pentylfuran (CAS 3777-69-3) is primarily used as an odorant and fragrance ingredient, supporting fruity or nutty notes in perfumery, cosmetics, and household cleaning products; it is also evaluated as a flavor component or modifier in the food-flavor sector. In addition, it serves as an organic-chemical intermediate for the synthesis of other fragrance compounds and related building blocks in industrial formulations. It may be studied as a precursor in polymer or resin chemistries for specialty applications, with usage governed by local regulations and formulation limits.
