  • Applications

    Dec-2-en-4-one, a ten-carbon alpha,beta-unsaturated ketone (CAS 63024-86-2), is primarily used as a fragrance intermediate and odorant in perfumery, contributing green-to-floral notes in various formulations. It is also evaluated for cosmetics and personal care applications as a fragrance ingredient, and may appear in household products such as air fresheners and cleaners to enhance aroma. In industrial manufacturing, it serves as a building block for the synthesis of other fragrance chemicals and specialty materials, and can function as a reactive intermediate in related polymer, coatings, or ink formulations where a green scent is desired. Its use is typically formulation- and regulation-dependent, requiring appropriate handling and compliance with local restrictions.
