Used as a reagent in analytical chemistry for the detection and estimation of reducing sugars and other reducing substances. It serves as a precursor in the synthesis of copper-based catalysts and coordination compounds. Applied in electroplating processes to deposit copper films with controlled morphology due to its stable complexation behavior. Also utilized in educational laboratories for demonstrating coordination chemistry and redox reactions. Finds use in some formulations of nutritional supplements and agricultural micronutrient mixtures where controlled copper release is required.
