Used as a catalyst in organic synthesis, particularly in coupling reactions such as azide-alkyne cycloaddition (click chemistry), enabling efficient formation of triazole rings. Also serves as a precursor in the preparation of coordination polymers and metal-organic frameworks (MOFs) due to its stable pyridine ligands and accessible copper center. Applied in electrochemical systems for studying redox behavior of copper complexes. Its solubility in polar organic solvents makes it suitable for homogeneous catalysis in pharmaceutical and materials science research.
