Used as a catalyst in organic synthesis, particularly in oxidation reactions (such as the oxidation of alcohols to aldehydes or ketones) and coupling processes. Serves as a source of copper ions in electroplating and metal finishing applications. Employed in the preparation of other copper-based compounds and coordination complexes, including chelating agents used in materials science. Acts as an oxidizing agent in laboratory settings and in the synthesis of energetic materials, such as in fireworks ignition systems due to its ability to release oxygen. Also utilized in research involving ionic liquids and as a reagent in analytical chemistry for detecting specific functional groups. Handle with care as it is a strong oxidizing agent and may be explosive when in contact with flammable materials.
