Used in the synthesis of antiviral agents, particularly in the development of nucleoside analogs that inhibit viral RNA replication. Shows potential in targeting RNA viruses by acting as a prodrug component, interfering with viral polymerase activity. Investigated for use in treatments against certain enveloped viruses due to its ability to mimic natural nucleosides and induce chain termination during replication. Also explored for improved bioavailability and cell permeability in drug delivery systems targeting central nervous system infections.
