Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan, valsartan, and irbesartan, which are widely prescribed for hypertension and cardiovascular diseases. It serves as a bioisostere for carboxylic acid groups, improving metabolic stability and oral bioavailability in pharmaceutical compounds. Also employed in coordination chemistry as a ligand for metal ions due to its nitrogen-rich heterocyclic structure. Additionally, finds use in the development of energetic materials and corrosion inhibitors.
