Used as a key intermediate in the synthesis of sartan-class antihypertensive drugs, particularly in the preparation of valsartan and related angiotensin II receptor blockers. Its structure enables efficient coupling reactions in pharmaceutical manufacturing, contributing to the development of active pharmaceutical ingredients (APIs) with high selectivity and yield. The bromo and tetrazole functional groups provide sites for palladium-catalyzed cross-coupling, making it valuable in constructing complex drug molecules. Widely employed in research and industrial settings for developing cardiovascular medications.
