  • Applications

    Chemical name: 4-Nonenal, (4E)-; CAS number: 2277-16-9. 4-Nonenal, (4E)- is a C9 aldehyde predominantly used as a fragrance ingredient to impart green, aldehydic, fresh notes in perfumery and cosmetics, and it also functions as a fragrance additive in household products such as laundry detergents and floor cleaners. It may serve as an intermediate or precursor in industrial manufacturing for fragrance synthesis. In some cases, it is evaluated as a flavor/aroma component for limited food formulations. Use and concentration are subject to local regulations and formulation limits.
