  • Applications

    8-Nonenal (CAS 39770-04-2) is primarily used as an odorant and fragrance ingredient in perfumery, contributing an aldehydic green, fresh note and serving as a basis for the synthesis of other aroma compounds. In cosmetics and personal care, it is used as a fragrance component, providing characteristic aldehydic notes in perfumes, lotions, and soaps. In household and cleaning products, it may be added to enhance fragrance and a sense of freshness. It can also act as an intermediate in the synthesis of fragrance-related chemicals and is considered for applications in plastics or coatings formulations where odorant effects are desirable. Use is subject to local regulations and formulation limits.
