Used in coordination chemistry as a ligand for metal ions, particularly in the development of luminescent and redox-active complexes. Its bromine substituent allows for further functionalization via cross-coupling reactions, making it valuable in synthesizing advanced materials and catalysts. Commonly applied in the design of sensors for metal cations due to its strong chelating ability and signal-responsive behavior. Also employed in biochemical studies as a probe for DNA interactions and enzyme inhibition, leveraging its planar aromatic structure and binding affinity to nucleic acids.
