  • Applications

    Acetopropyl alcohol (CAS 1071-73-4) is primarily used as an industrial solvent and as an organic synthesis intermediate. It is commonly employed as a solvent and diluent in coatings, inks, and adhesives formulations, and can function as a surface-treatment agent in material processing. It also serves as a precursor for other organic compounds and participates in polymer and plastics manufacturing.
