  • Applications

    3,6-Nonadienal (CAS 78263-66-8) is an aldehyde with a cucumber-like aroma that is widely used as a fragrance and flavor ingredient. In practice, it is commonly employed as an odorant in perfumery to impart cucumber notes and is added to flavor formulations to reinforce cucumber-like flavors. It is also used in cosmetics and personal care to provide a fresh, cucumber-like scent and in household products such as cleaners and air fresheners to enhance aroma. Its use may be subject to local regulations and formulation limits.
