  • Applications

    Heptyl isobutyrate, CAS 2349-13-5, is an ester of isobutyric acid and heptanol. In industry it is commonly used as a fragrance ingredient and fixative in perfumery, and it can also function as a solvent or co-solvent in cosmetic and personal care formulations and in some household products. It may be used as a processing aid or solvent in coatings and inks, and can serve as an intermediate in organic synthesis for industrial manufacturing or as a component in polymer formulations to influence texture and odor. Its use is subject to local regulations and formulation limits.
