Used as a key intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like valsartan and related sartan-class medications. Its structure allows for effective coupling in biphenyl-based pharmaceuticals, enhancing binding affinity to the AT1 receptor. Commonly employed in API manufacturing due to its reactive nitrile group and halogenated aromatic ring, facilitating further functionalization through cross-coupling reactions. Also utilized in research for developing new cardiovascular therapeutics.
