Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of selective enzyme inhibitors and antitumor agents. Its structure supports the creation of heterocyclic compounds with enhanced metabolic stability and binding affinity. Commonly employed in medicinal chemistry for constructing thiosemicarbazide-based bioactive molecules. Also utilized in the preparation of fluorescent probes for biological imaging due to the electron-withdrawing fluorine atoms improving photostability.
