Used as a key 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 the introduction of fluorine and methylamino groups, which can enhance metabolic stability and binding affinity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate electronic and steric properties in aromatic systems. Also utilized in the preparation of selective enzyme inhibitors and receptor ligands.
