Used as a ligand in coordination chemistry, particularly in the synthesis of transition metal complexes for catalytic applications. Its bromo substituent allows for further functionalization via cross-coupling reactions, making it valuable in the development of advanced catalysts for organic transformations. Commonly employed in ruthenium- and iridium-based complexes used in photoredox catalysis and luminescent materials. Also finds use in the preparation of metallo-supramolecular architectures due to its rigid bipyridyl backbone and selective metal-binding properties.
