Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs. Its structure allows for selective modification to develop compounds that block the action of angiotensin II, a substance in the body that causes blood vessels to constrict. By inhibiting this effect, medications derived from this chemical help lower blood pressure and reduce the risk of cardiovascular events such as stroke and heart attack. It is primarily employed in pharmaceutical research and development for creating sartan-class drugs.
