  • Applications

    4,9-Decadienal, 2,4,8-trimethyl-, CAS 72928-00-8 is primarily employed as a fragrance-related chemical. In perfumery and cosmetics, it functions as an odorant and note modifier to contribute aldehydic, green note characteristics and depth in fragrance formulations; it can also serve as an intermediate in the synthesis of other aroma compounds. In household products, it is used to impart distinctive scents in air fresheners and cleaners. In industrial manufacturing, it can act as an intermediate or starting material for fragrance ingredient production. It may be incorporated into coatings, inks, and adhesives as a fragrance additive to improve odor profiles. Use is subject to local regulations and formulation limits.
