  • Applications

    2-Ethylidenedecan-1-al (CAS 64825-20-3) is primarily used as an aroma ingredient or fragrance intermediate in the fragrance, cosmetics, and household products sectors, providing long-chain aroma notes in fine perfumes and personal care formulations. It may also serve as a reactive intermediate in industrial manufacturing to access other long-chain aldehydes and fragrance-related compounds. Additionally, it can be evaluated for use in coatings and inks as a fragrance additive, and in household cleaning products to impart a lasting scent, all subject to local regulations and formulation limits.
