Used as an intermediate in the synthesis of liquid crystal materials for display technologies. Plays a key role in pharmaceutical manufacturing, particularly in the development of angiotensin II receptor antagonists used to treat hypertension. Also employed in the production of advanced organic semiconductors and functional polymers due to its rigid biphenyl backbone and reactive functional groups. Its aldehyde and carboxylic acid moieties allow for further chemical modifications, making it valuable in research and development of new bioactive compounds and specialty chemicals.
