Used as a precursor in sol-gel processes for preparing copper-containing oxide materials, particularly in the synthesis of copper oxide thin films for semiconductor and catalytic applications. It serves as a source of copper in the fabrication of electronic ceramics and conductive coatings. Its reactivity makes it suitable for homogeneous catalysis in organic transformations, including oxidation reactions. Also employed in research settings for the development of nanomaterials and functional surfaces requiring controlled copper deposition.
