Widely used as a ligand in coordination chemistry, enabling the formation of stable complexes with transition metals for catalytic applications. Its derivatives are employed in the development of photoredox catalysts, which play a key role in organic synthesis under light irradiation. Also utilized in the design of sensors for metal ion detection due to its selective binding and optical response. Applied in material science for constructing metal-organic frameworks (MOFs) and functional thin films. Additionally, it serves as a building block in the synthesis of pharmaceuticals and agrochemicals where nitrogen-oxygen donor systems enhance biological activity.
