Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor blockers (ARBs) like valsartan and related antihypertensive drugs. Its stereochemistry plays a critical role in the biological activity of the final drug product. Commonly employed in asymmetric synthesis and resolution processes to ensure high enantiomeric purity. Also utilized in the development of liquid crystal materials due to its rigid biphenyl structure and chiral center, making it suitable for optoelectronic applications.
