Used primarily as an intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals. It serves as a building block in the preparation of certain antitumor agents and antiviral compounds due to its structural similarity to natural pyrimidines, allowing incorporation into nucleic acid analogs. Its fluorine substituent enhances metabolic stability and binding affinity in biologically active molecules. Also employed in research for developing new fluorinated heterocyclic compounds with potential medicinal properties.
