  • Applications

    Oleanoaldehyde (CAS 19132-81-1) may be used as a fragrance ingredient and odorant in perfumery and scented products; it can serve as an intermediate in the industrial synthesis of fragrance and flavor compounds; it may be employed in cosmetics and personal care formulations as a fragrance component; it may contribute as an odorant in household products such as cleaners and air fresheners; and in industrial manufacturing it is sometimes evaluated as a chemical intermediate for fragrance-related syntheses in specialty coatings or inks.
