Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its dual carboxylic acid functionality and fluorine substitution make it valuable for constructing complex aromatic frameworks with enhanced metabolic stability and binding affinity. Commonly employed in coupling reactions to form amide or ester linkages in drug candidates. Also utilized in the preparation of fluorinated ligands for medicinal chemistry research, where the fluorine atoms improve pharmacokinetic properties.
