Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive agents and angiotensin II receptor antagonists. It serves as a building block for introducing the 4-bromo-3-chlorophenyl moiety into more complex molecules, enabling the development of active drug substances. Its nitrile group allows for further functionalization, such as hydrolysis to carboxylic acids or reduction to amines, making it valuable in medicinal chemistry and process development. Also utilized in the preparation of agrochemicals and bioactive compounds where halogenated aromatic structures are required for activity.
