Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as candesartan and valsartan. Its bromo and tetrazole functionalities allow for selective cross-coupling reactions and bioisosteric replacement of carboxylic acid groups, enhancing metabolic stability and binding affinity to the AT1 receptor. Commonly employed in pharmaceutical research and development for optimizing drug candidates targeting cardiovascular diseases. Also utilized in agrochemicals for developing bioactive molecules due to its aromatic and heterocyclic character.
