  • Applications

    N-Isopentylacetamide (CAS 13434-12-3) is used as an organic intermediate and processing solvent in industrial manufacturing, where it can function as a solvent or carrier in chemical syntheses and formulation work. In fragrance and perfumery, it may serve as an odor-active ingredient or fragrance fixative. In cosmetics and personal care, it can act as a solvent or processing aid for formulations. In polymers, plastics, and coatings, it is considered a synthesis precursor for amide-derived materials and can serve as a processing aid to adjust solvency and rheology.
