  • Applications

    Nonanal dimethyl acetal (CAS 18824-63-0) is used primarily in fragrance chemistry as an odorant and building block for related aroma compounds; it also serves as an aldehyde-protecting intermediate in multi-step fragrance synthesis, enabling controlled release or subsequent conversion to nonanal under acidic conditions; in industrial manufacturing it may be incorporated into fragrance formulations for household products where local regulations permit; it is likewise evaluated for flavor/fragrance research as a potential aroma chemical.
