Used as a precursor in the synthesis of copper-based nanomaterials for electronics and catalysis. Applied in electroplating processes to deposit thin copper films on substrates for printed circuit boards. Employed in agricultural formulations as a micronutrient supplement in fertilizers to correct copper deficiency in soils. Utilized in wood preservation treatments to protect against fungal decay and insect damage. Serves as a reagent in analytical chemistry for detecting reducing sugars and in the preparation of other copper compounds. Also used in some antimicrobial coatings and solutions due to copper’s biocidal properties.
