Used in pharmaceutical synthesis as a key intermediate for angiotensin II receptor antagonists, such as sartan-class drugs (e.g., valsartan, losartan), which are widely prescribed for hypertension and cardiovascular diseases. The tetrazole group mimics the carboxylic acid functionality, improving metabolic stability and bioavailability. Also employed in coordination chemistry as a ligand for metal complexes due to its nitrogen-rich heterocyclic structure. Shows potential in materials science for developing energetic materials and corrosion inhibitors.
