Used in electroplating processes to deposit copper onto surfaces for improved electrical conductivity and corrosion resistance. Commonly employed in the production of catalysts, especially in organic synthesis and industrial chemical reactions. Serves as a precursor in the preparation of copper oxide nanoparticles for electronic and antimicrobial applications. Utilized in textile printing and dyeing as a mordant to fix colors on fabrics. Applied in educational and research laboratories for demonstrations and experiments involving redox reactions and metal ion behavior. Also used in etching formulations for printed circuit boards in electronics manufacturing.
