Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the preparation of sartan-class antihypertensive drugs such as losartan and valsartan. Its structure allows for effective binding to biological targets involved in blood pressure regulation. Commonly employed in pharmaceutical research and development for designing potent and selective inhibitors of the renin-angiotensin system. Also utilized in medicinal chemistry for constructing heterocyclic frameworks with improved metabolic stability and bioavailability.
