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 pyridyl and tetrazole groups mimic the carboxylate group in angiotensin II, enabling effective binding to the AT1 receptor. Also employed in coordination chemistry as a ligand for metal-organic frameworks (MOFs) due to its ability to chelate metal ions. Additionally, finds use in materials science for developing conductive polymers and corrosion inhibitors.
