Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as losartan and valsartan. Its tetrazole ring serves as a bioisostere for the carboxylic acid group, enhancing metabolic stability and improving pharmacokinetic properties. Commonly employed in pharmaceutical research and development for optimizing drug candidates targeting cardiovascular diseases. Also utilized in coordination chemistry as a ligand due to its nitrogen-rich structure, enabling complexation with metal ions for catalytic or material applications.
