  • Applications

    Isodecylaldehyde, CAS 3085-26-5, is primarily used as a fragrance intermediate and odorant in perfumery, contributing woody and amber notes and serving as a building block for many complex aroma compounds. It is commonly evaluated for use in cosmetics and personal care products as a fragrance ingredient, and in household products and cleaning formulations to impart a characteristic scent. In industrial manufacturing, it serves as an intermediate for the synthesis of specialty fragrance chemicals and aroma components, and may be incorporated into coatings and inks as a fragrance additive, subject to formulation and regulatory limits.
