Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its bromo and methoxy functional groups allow for selective cross-coupling reactions, making it valuable in the preparation of bioactive molecules. Commonly employed in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other therapeutic agents where phenylacetic acid derivatives are active components. Also utilized in research settings for constructing complex aromatic structures through palladium-catalyzed reactions.
