Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like valsartan and related antihypertensive drugs. Its functional groups—cyano, ester, and methoxy—allow for selective chemical transformations, making it valuable in building complex drug molecules. Commonly employed in coupling reactions and heterocycle formation during active pharmaceutical ingredient (API) development. Also utilized in research settings for designing novel bioactive compounds due to its aromatic and electron-withdrawing group arrangement.
