  • Applications

    3(2H)-Furanone, 2-methyl- is typically used as an aroma- and fragrance-building block in perfumery and cosmetic formulations, contributing fruity, creamy notes. It is often employed as an intermediate in the synthesis of other furanone-based fragrance compounds and may serve as a flavor/aroma ingredient in food and beverage systems where permitted. It can also function as a scent additive in household products, detergents, and coatings, and may be pursued as a specialty intermediate in industrial manufacturing for odor profiles. Use is subject to local regulations and formulation limits.
