Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like losartan and other sartan-class drugs. It plays an essential role in forming the imidazole ring core structure that contributes to the biological activity of these antihypertensive agents. Also utilized in the development of agrochemicals and functional materials due to its reactive nitrile group and aromatic framework. Its structure allows for further chemical modifications, making it valuable in medicinal chemistry research and drug discovery processes.
