Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and valsartan, which are widely prescribed for the treatment of hypertension and heart failure. Its tetrazole ring mimics the carboxylic acid group in biological systems, enhancing binding affinity to the receptor. Also employed in the development of other pharmaceuticals and agrochemicals due to its ability to participate in coordination and hydrogen bonding. Additionally, finds use in materials science for constructing nitrogen-rich polymers and ligands in catalysis.
