Used primarily as a chemical intermediate in the synthesis of liquid crystal materials for display technologies. It serves as a building block in organic semiconductors and is involved in the production of advanced polymers with unique electro-optical properties. Its rigid biphenyl structure contributes to thermal stability and molecular alignment in thin-film applications. Also explored in pharmaceutical research for modifying drug candidates to improve lipophilicity and bioavailability. Commonly employed in cross-coupling reactions to construct complex aromatic systems in medicinal chemistry and materials science.
