Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs such as losartan and valsartan. Its thiol and tetrazole functionalities enhance binding affinity to the angiotensin receptor, improving drug efficacy. Also employed in coordination chemistry as a ligand for metal ions due to its sulfur and nitrogen donor sites, useful in catalysis and material science. Additionally, shows potential in corrosion inhibition for metals in industrial systems.
