Used as a multidentate ligand in coordination chemistry, this compound forms stable complexes with transition metals due to its four nitrogen donor sites and chelating pyridyl groups. It is employed in catalysis, particularly in reactions like oxidation and C–C bond formation, where metal-ligand cooperation enhances activity and selectivity. Its rigid structure and electron-donating properties make it suitable for designing functional metallo-supramolecular assemblies and sensors. Additionally, it has been explored in biomimetic studies and as a scaffold in the development of catalysts for asymmetric synthesis.
