  • Applications

    For the chemical 9-Decen-5-olide (CAS 74585-00-5), a gamma-lactone, applications span fragrance and flavor sectors: it is used as an odorant and fragrance ingredient in perfumery, and is evaluated for flavor/aroma uses in food and beverage contexts. In cosmetics and personal care, it serves as a scent component in creams, lotions, and cleansers. The lactone can be synthesized or used as an intermediate in organic synthesis, including production of functionalized polymers such as aliphatic polyesters and other lactone-derived monomers. In industrial manufacturing, it may function as an intermediate for specialty esters or fragrance-release additives. It may also appear in formulated household products as a fragrance ingredient, subject to local regulations and formulation limits.
