Used as a key intermediate in the synthesis of nitrogen-containing heterocyclic compounds, particularly in the development of ligands for catalytic metal complexes. Its aldehyde functional groups allow for easy modification through condensation or reduction reactions, making it valuable in constructing Schiff bases and other functionalized bipyridine derivatives. Commonly employed in coordination chemistry to prepare transition metal complexes for applications in catalysis, luminescent materials, and sensors. Also finds use in organic electronics and as a building block in supramolecular chemistry due to its rigid, planar structure and ability to chelate metals.
