  • Applications

    2(3H)-Furanone, dihydro-3-propyl- is primarily used as an aroma chemical and fragrance intermediate in the flavor and perfumery industries, where it can contribute fruity, lactone-like notes in formulations; it is commonly evaluated for use in flavorings to enhance fruit profiles and as a fragrance ingredient in cosmetics and personal care products. It may also find applications in household products (air fresheners and cleaners) as an odorant additive. In industrial manufacturing, it is employed as an intermediate for the synthesis of more complex fragrance and flavor compounds. The use is subject to regulatory limits and formulation requirements.
