Used as a ligand in coordination chemistry, particularly in catalysis and transition metal complex formation. Its nitrogen donor sites enable stable chelation with metals, making it valuable in designing catalysts for organic transformations such as C–H activation and cross-coupling reactions. Also applied in materials chemistry for developing luminescent complexes and sensors due to its ability to modulate electronic properties of metal centers. Additionally, it serves as a building block in supramolecular chemistry for constructing metallo-receptors and molecular assemblies.
