Used as a key intermediate in the synthesis of certain pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs). Its structure allows for the formation of active metabolites that contribute to the inhibition of cyclooxygenase enzymes, reducing inflammation and pain. Also employed in the preparation of specialty polymers and functionalized molecules for use in medicinal chemistry research. Its amino and carboxylic acid groups enable coupling reactions, making it valuable in building complex drug-like molecules.
