Used primarily as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like valsartan. Its structure enables effective binding to biological targets involved in blood pressure regulation. This compound plays a critical role in developing medications that treat hypertension and heart failure by blocking the action of angiotensin II, a substance that narrows blood vessels. Its tetrazole group mimics the carboxylic acid functionality, enhancing metabolic stability and bioavailability in final drug formulations.
