Used in the synthesis of pharmaceutical intermediates, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its aromatic structure and functional group compatibility. Also employed in the development of agrochemicals and specialty polymers where a substituted phenylacetic acid moiety is required. Its methyl substituents enhance lipophilicity, making it useful in modifying drug absorption and metabolic stability.
