Used as a versatile ligand in coordination chemistry, particularly in catalysis and metal complex formation. Its structure allows for strong chelation of metal ions, making it effective in homogeneous catalysis for reactions such as oxidation, epoxidation, and C–C bond formation. Commonly employed in the development of catalysts for industrial and fine chemical synthesis due to its ability to stabilize active metal centers. Also finds use in polymer chemistry as a curing agent or cross-linking promoter. In research, it serves as a building block for designing multifunctional complexes in supramolecular chemistry and sensor systems.
