Used as an intermediate in the synthesis of antiviral agents, particularly in the preparation of nucleoside analogs. Its structure supports selective protection of hydroxyl groups, enabling precise modification in multi-step organic syntheses. Commonly employed in the development of pharmaceuticals targeting RNA viruses, where fluorinated sugar moieties enhance metabolic stability and bioavailability. Ideal for constructing complex nucleoside scaffolds due to its stereochemical control and compatibility with coupling reactions.
