Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, such as losartan and valsartan, which are widely prescribed for hypertension treatment. Its thiol and tetrazole groups enhance binding affinity to biological targets and improve metabolic stability. Also employed in coordination chemistry as a ligand for metal ions, forming complexes with potential catalytic or antimicrobial properties. Additionally, finds use in material science for developing heterocyclic polymers and corrosion inhibitors.
