Used in organic synthesis as an intermediate for pharmaceuticals and advanced materials. Serves as a building block in the preparation of liquid crystals and organic semiconductors due to its rigid aromatic structure. Employed in cross-coupling reactions, such as Suzuki or Ullmann reactions, to construct complex biaryl systems for optoelectronic devices. Also investigated in the development of functional polymers and ligands for catalysis. Its halogen substituents allow selective functionalization, making it valuable in fine chemical synthesis. Handle with care due to potential toxicity and environmental hazards.
