  • Applications

    Cupric citrate is the copper(II) citrate salt. It is commonly used as a chelating/complexing agent to sequester metal ions in chemical formulations and as a sequestrant in cleaning products. It also serves as a copper source for micronutrient fertilizer formulations in agriculture. In industrial contexts it may act as a catalyst or cocatalyst in certain synthesis and manufacturing processes. It can function as a stabilizing component in some polymer formulations and may be used as a copper ion source for coatings or conductive inks in electronics and related coatings. Its use as an intermediate in chemical synthesis is also possible, depending on formulation and regulations.
