Used primarily as an intermediate in the synthesis of angiotensin II receptor antagonists, such as valsartan and related sartan-class antihypertensive drugs. Its tetrazole group mimics the carboxylate group in angiotensin II, enabling effective binding to the AT1 receptor. The biphenyl methanol structure provides a rigid scaffold that enhances selectivity and potency. It is valuable in pharmaceutical development for creating potent, orally active agents that lower blood pressure by blocking vasoconstriction and aldosterone release.
