Used as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like telmisartan. Its structure supports the development of compounds that block the action of angiotensin II, a substance in the body that constricts blood vessels and raises blood pressure. Due to its carboxylic acid and imidazole functional groups, it enables key molecular interactions in drug design, enhancing binding affinity and metabolic stability. Commonly employed in pharmaceutical research and development for cardiovascular medications.
