Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of nucleoside analogs targeting RNA viruses. Its structure enables selective modification for improved bioavailability and metabolic stability in prodrug strategies. Commonly employed in research for hepatitis C and coronaviruses due to its ability to mimic natural nucleosides, interfering with viral replication. Also utilized in medicinal chemistry for optimizing drug candidates with enhanced cell penetration and reduced toxicity.
