Used as a fungicide in agriculture, particularly in vineyards and orchards to control fungal diseases, often applied as a foliar spray or soil amendment. It is also employed in electroplating processes to deposit copper coatings on various substrates. In laboratories, it serves as a source of copper ions in analytical chemistry, as a starting material for synthesizing other copper compounds in inorganic chemistry, and sometimes as a catalyst in specific chemical processes. Additionally, it finds use in textile printing, as a mordant in dyeing processes to help fix colors on fabrics, and to improve fiber durability.
