Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as valsartan and losartan. Its structure enables efficient coupling in heterocyclic ring formation, making it valuable in pharmaceutical development for cardiovascular medications. Also employed in organic synthesis for constructing nitrogen-containing heterocycles due to the reactivity of the tetrazole ring and bromo substituent, which allows further functionalization through cross-coupling reactions.
