Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like losartan and candesartan, which are widely prescribed for hypertension and cardiovascular diseases. Its tetrazole ring serves as a bioisostere for carboxylic acid groups, enhancing metabolic stability and improving bioavailability in drug molecules. Due to its high nitrogen content and stable structure, it is also utilized in the explosives industry as a precursor for synthesizing high-energy, low-smoke heterocyclic compounds. Additionally, it is employed in coordination chemistry as a ligand for transition metal ions in catalytic systems and functional materials, including magnetic materials.
