Used as a key intermediate in the synthesis of advanced organic semiconductors and liquid crystal materials. Its halogen substitution pattern allows for selective cross-coupling reactions, making it valuable in the preparation of conjugated polymers and optoelectronic materials. Commonly employed in Suzuki and Ullmann coupling reactions to build complex aromatic frameworks for use in organic light-emitting diodes (OLEDs) and thin-film transistors. Also finds application in the development of specialty dyes and high-performance polymers due to its rigid biphenyl core and functional versatility.
