Used as a key ligand in coordination chemistry, particularly in the development of catalytic systems for cross-coupling reactions. Its nitrile group enhances metal binding properties, making it effective in stabilizing transition metal complexes used in organic synthesis and industrial catalysis. Also employed in the design of luminescent materials and sensors due to its ability to form complexes with metal ions that exhibit photophysical activity. Additionally, it serves as a building block in the synthesis of functionalized bipyridines for use in electrochemical applications, including dye-sensitized solar cells and molecular electronics.
