Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of nucleoside analogs targeting RNA viruses. Its structure supports binding to viral polymerase enzymes, making it valuable in medicinal chemistry for designing inhibitors. Also employed in research for novel kinase inhibitors due to the pyrimidine core's affinity for ATP-binding sites. The fluorinated aryl group enhances membrane permeability, improving cellular uptake in drug candidates.
