Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of fungicides and herbicides. Its nitrile and bromo functional groups allow for versatile chemical transformations, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build biaryl structures. Also utilized in the preparation of bioactive compounds and functional materials where substituted benzonitriles are required.
