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. It contributes to the formation of the tetrazole ring, which is essential for the biological activity of these medications by enhancing binding affinity to the angiotensin II receptor. Also employed in coordination chemistry as a ligand for metal ions in catalytic systems. Shows potential in energetic materials research due to the high nitrogen content and thermal stability of the tetrazole core.
