Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its fluorinated cyclic structure enhances metabolic stability and binding affinity in drug molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate polarity and lipophilicity. Also utilized in the preparation of fluorinated building blocks for PET tracer development and other bioactive compounds.
