Used as an intermediate in the synthesis of antiviral drugs, particularly in the development of nucleoside analogs targeting RNA viruses. Its structure allows for selective modification to enhance bioavailability and metabolic stability in prodrug formulations. Commonly employed in research settings for designing inhibitors of viral polymerases. Shows potential in oncology-related drug discovery due to its ability to mimic natural nucleosides and interfere with DNA/RNA synthesis in rapidly dividing cells.
