  • Applications

    2,4,6,8-Undecatetraenal (CAS 108670-79-7) is an unsaturated aldehyde with four double bonds, primarily considered as a fragrance material and chemical intermediate in the fragrance, cosmetics, and related industries. It is commonly used as a building block for the synthesis of aroma compounds and contributes aldehydic notes in fragrance formulations. It may also serve as a precursor in aroma chemistry for industrial applications and can be incorporated into cosmetics and personal care products to impart or enhance scent. In household products, detergents and cleaners may include it as a scented ingredient. Additionally, it is used as an intermediate for specialty aroma compounds in industrial manufacturing and can participate in polymer, coating, and plastics formulation where aldehyde functionality is desired, subject to regulatory and formulation limits.
