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 structure allows for enhanced metabolic stability and improved binding affinity in drug candidates. The presence of fluorine atoms increases lipophilicity and resistance to oxidative degradation, making it valuable in medicinal chemistry for optimizing pharmacokinetic properties. Also employed in the preparation of chiral building blocks for asymmetric synthesis in drug discovery.
