Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 inhibitors. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building bioactive molecules. Also employed in the preparation of agrochemicals and specialty heterocyclic compounds. Its carboxylic acid group facilitates conjugation and salt formation, enhancing solubility and stability in drug formulations.
