Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows for strong chelation with transition metals, making it valuable in homogeneous catalysis such as cross-coupling reactions and oxidation processes. Also employed in the development of luminescent materials and sensors due to its ability to enhance the photophysical properties of metal complexes. Additionally, it serves as a building block in the synthesis of more complex bipyridine derivatives for use in organic electronics and supramolecular chemistry.
