Used primarily in organic synthesis as an intermediate for cross-coupling reactions, especially in the development of advanced materials such as organic semiconductors and OLEDs. Its bromine functionality allows it to participate in palladium-catalyzed reactions like Suzuki or Heck couplings, enabling the construction of complex aromatic frameworks. The presence of both chlorophenyl and phenyl groups provides steric bulk and electronic properties that enhance performance in optoelectronic devices. It is also employed in the synthesis of ligands and functionalized fluorene derivatives for use in polymer-based electronics.
