Used as a catalyst in organic synthesis, particularly in oxidation reactions and coupling processes. It serves as a source of copper ions in electroplating and metal finishing applications. Also employed in the preparation of other copper-based compounds and materials, including those with magnetic or electronic properties. Due to its strong oxidizing properties, it is utilized in pyrotechnics and propellants for generating heat and gas. It exhibits good solubility in various solvents, providing highly reactive Cu²⁺ ions. Commonly used in laboratory research for studying redox reactions, coordination chemistry, and the behavior of transition metal ions under different conditions.
