Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like telmisartan. Its structure allows for the formation of biaryl systems that are essential for binding to the angiotensin II receptor. Commonly employed in pharmaceutical research and development for creating potent, long-acting blood pressure medications. Also utilized in the preparation of other bioactive molecules where a biphenyl scaffold with functionalized side chains is required.
