Used as a key intermediate in the synthesis of ligands for transition metal catalysts, particularly in cross-coupling reactions. Plays a role in the preparation of functionalized bipyridine derivatives that serve in coordination chemistry, including ruthenium- and iridium-based complexes for photovoltaic devices and luminescent materials. Also employed in the development of sensors and molecular electronics due to its ability to form stable complexes with metal ions. Its bromo group allows for further functionalization via palladium-catalyzed coupling reactions, making it valuable in organic synthesis and materials science.
