  • Applications

    Nonadecanal (CAS 17352-32-8) is a long-chain aliphatic aldehyde that is primarily used as a fragrance ingredient in perfumery. In practice it can serve as a scent component and, owing to its high molecular weight, may act as a moderate fixative in fragrance formulations. It is commonly evaluated for use in cosmetics and personal care products as an aroma ingredient, and in household products such as cleaners and air fresheners to impart fragrance. Additionally, it serves as an intermediate in industrial manufacturing for the synthesis of fragrance-related esters and other specialty chemicals, and may be used in coatings and inks as a fragrance additive. Applications are subject to local regulations and formulation limits.
