Used primarily in the pharmaceutical industry as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs. It plays a key role in developing medications that manage high blood pressure and related cardiovascular conditions by blocking the action of angiotensin II, a substance that narrows blood vessels. Due to its functional groups, including the tetrazole ring and pyrimidine core, it enhances binding affinity to biological targets, improving drug efficacy. Its structure supports metabolic stability and bioavailability in final drug formulations.
