Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the development of sartan-class antihypertensive drugs such as candesartan and valsartan. Its structure enables effective binding to the AT1 receptor, helping block vasoconstriction and aldosterone release. Also employed in medicinal chemistry research for designing new bioactive molecules due to its ability to act as a carboxylic acid bioisostere, improving metabolic stability and oral bioavailability in drug candidates.
