  • Applications

    Cupric acetate (CAS 142-71-2) is a versatile copper(II) salt used in industrial and laboratory contexts. In coatings and paints, it acts as a drying catalyst to promote oxidative curing of alkyd resins and related formulations, improving film formation and hardness. In polymer and plastics manufacturing, it serves as a catalyst or co-catalyst in certain oxidation and coupling processes, enabling controlled polymerization and processing. In organic synthesis, it functions as a reagent and catalyst for oxidative transformations and various copper-catalyzed reactions. In the laboratory and process chemistry settings, it is widely employed as a copper source and a practical starting material for preparing copper complexes or other copper salts. In agriculture, cupric acetate may be formulated and used as a copper-based fungicide in some crop protection products, subject to regulatory requirements.
