Used as a ligand in coordination chemistry, 2,2'-Bipyrazine forms stable complexes with transition metals, which are applied in catalysis and materials science. Its nitrogen-rich structure makes it valuable in the development of luminescent compounds and metal-organic frameworks (MOFs). It is also employed in electrochemical sensors due to its ability to facilitate electron transfer. Additionally, it serves as a building block in synthesizing functional polymers and supramolecular systems with potential uses in optoelectronics and molecular devices.
