Used in the synthesis of pharmaceutical intermediates, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). Its structure supports the development of active compounds that inhibit cyclooxygenase enzymes, contributing to anti-inflammatory, analgesic, and antipyretic effects. Commonly employed in fine chemical manufacturing for building complex drug molecules due to its reactive carboxylic acid group and aromatic backbone. Also utilized in research settings for developing fluorinated analogs to improve metabolic stability and bioavailability in new drug candidates.
