Used as a ligand in coordination chemistry to form metal complexes with catalytic activity, particularly in palladium-catalyzed cross-coupling reactions. Its brominated aromatic structure enhances electronic tuning of the metal center, improving selectivity and efficiency in catalysis. Also employed in the development of luminescent materials and sensors due to its ability to chelate transition metals like ruthenium and iridium, which are key in photophysical applications. Additionally, it serves as a building block in supramolecular chemistry for constructing metallo-receptors and molecular devices.
