Used as an intermediate in organic synthesis, particularly in the preparation of liquid crystals and advanced aromatic materials. Its brominated structure enables coupling reactions, such as Suzuki or Ullmann reactions, to build complex terphenyl-based frameworks. Commonly applied in the development of organic semiconductors, optoelectronic materials, and specialty polymers due to its rigid, conjugated backbone and functional handle for further modification. Also explored in the synthesis of ligands for catalysis and in materials science for tuning molecular packing and thermal stability.
