  • Applications

    Cupric citrate hemipentahydrate, CAS 6020-30-0, is used as a copper micronutrient source in agriculture and animal feeds, delivering copper for enzymatic function and plant health; it is also regarded as a soluble and stable copper source. It acts as a chelating agent to sequester metal ions in water treatment systems and in industrial cleaning formulations. In industrial manufacturing and coatings, it serves as a copper precursor for copper-containing materials used in inks, paints, and electronic-grade materials. It can also function as a stabilizer or intermediate in polymer and plastics processing through catalytic or complexation pathways. Uses should comply with local regulations and formulation limits.
