Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antihypertensive and antiarrhythmic drugs. It serves as a building block in organic reactions where the nitrile group can be transformed into carboxylic acids or other functional groups, enabling the construction of more complex molecules. Its bromo and methoxy substituents allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for developing bioactive compounds. Also employed in the preparation of agrochemicals and functional materials due to its reactive sites and structural stability.
