  • Applications

    Non-2-enal (CAS 2463-53-8) is primarily used as a fragrance ingredient and odorant in perfumery and cosmetics, contributing green, aldehydic notes to formulations. It is commonly evaluated as a building block or intermediate in aroma-chemical synthesis, enabling routes to related aldehydes and esters used in fragrance applications. In household products, it may appear as a fragrance component in air fresheners, cleaners, and laundry detergents. It can also serve in industrial manufacturing as a reactive intermediate for aroma-chemical synthesis and, with formulation control, may be incorporated into specialty coatings or inks where a light aldehydic note is desirable. Subject to local regulations and formulation limits.
