Used in the synthesis of angiotensin II receptor antagonists, particularly in the development of sartan-class antihypertensive drugs. The tetrazole ring serves as a bioisostere for the carboxylic acid group, enhancing metabolic stability and improving pharmacokinetic properties. Its bromo-substituted biphenyl structure allows for further functionalization through cross-coupling reactions, making it a valuable intermediate in medicinal chemistry for drug design and optimization.
