Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of angiotensin II receptor antagonists like candesartan and related sartan-class drugs for treating hypertension. Its tetrazole ring serves as a bioisostere for the carboxylic acid group, improving metabolic stability and bioavailability. Also employed in coordination chemistry as a ligand for metal ions in catalytic systems. Shows potential in agrochemicals and materials science due to its thermal stability and ability to form hydrogen bonds.
