Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its aromatic and functional group arrangement, which allows for further chemical modifications. Also employed in the development of agrochemicals and specialty organic compounds where substituted benzoic acid derivatives are required. Its methoxy and carboxylic acid groups enable esterification and coupling reactions in fine chemical manufacturing.
