Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs. It plays a key role in constructing active pharmaceutical ingredients due to its reactive chlorine atoms, which allow for further functionalization in multi-step organic reactions. Commonly employed in the development of angiotensin II receptor antagonists, aiding in the creation of medications for high blood pressure. Its structure supports selective derivatization, making it valuable in medicinal chemistry for optimizing drug potency and metabolic stability.
