Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and other sartan-class antihypertensive drugs. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing metabolic stability and improving bioavailability. Commonly employed in pharmaceutical research to develop potent, selective agents for treating high blood pressure and cardiovascular diseases. Also utilized in coordination chemistry as a ligand due to its nitrogen-rich structure, forming stable complexes with metal ions for potential use in catalysis or material science.
