  • Applications

    Chemical name: 2(3H)-Furanone, dihydro-5-undecyl-; CAS 7370-42-5 is primarily used as a fragrance ingredient and odorant, imparting fruity peach-like notes in perfumery and cosmetics/personal care, and it may also serve as a fragrance fixative due to its long undecyl side chain. It can be employed as an intermediate in fragrance chemistry to synthesize more complex aroma compounds, and it may appear in household products and cleaning formulations as a fragrance additive. Evaluation for food flavor applications is possible under regulatory guidance, and its use is subject to local regulations and formulation limits.
