Used in the synthesis of pharmaceutical intermediates, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its functional groups allow for selective modifications in organic reactions, making it valuable in constructing complex aromatic compounds. Commonly employed in cross-coupling reactions and as a building block in medicinal chemistry for introducing substituted phenylacetic acid moieties. Also utilized in research settings for developing new analogs with potential therapeutic activity.
