Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require substituted phenylacetonitrile derivatives. Its bromo and methoxy functional groups allow for selective cross-coupling reactions, making it valuable in constructing complex organic molecules. Commonly employed in the development of central nervous system (CNS) agents and anti-inflammatory compounds due to its ability to modulate biological activity when incorporated into larger structures. Also utilized in research settings for the preparation of novel heterocyclic compounds through cyclization and nucleophilic substitution reactions.
