Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its fluorinated aromatic structure enhances metabolic stability and influences binding affinity to target enzymes. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the electron-withdrawing effects of fluorine atoms, which modulate acidity and lipophilicity. Also utilized in the preparation of chiral building blocks for asymmetric synthesis.
