Used as an intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of sartan-class antihypertensive drugs. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for developing compounds that block the angiotensin II type 1 (AT1) receptor. Commonly employed in research and industrial settings to construct key pharmacophores in cardiovascular therapeutics. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies.
