Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex aromatic compounds. Commonly employed in coupling reactions to form amide or ester derivatives for drug discovery research. Also utilized in the preparation of fluorescent probes and dyes due to its aromatic amine functionality.
