Used as an intermediate in the synthesis of antiviral medications, particularly in the production of nucleoside analogs. Its fluorinated sugar-like structure enables it to mimic natural nucleosides, making it valuable in drugs that inhibit viral replication. Commonly applied in the development of treatments for RNA viruses, where it contributes to improved metabolic stability and bioavailability of the active pharmaceutical ingredient. Also utilized in research settings to explore new antiviral agents with enhanced resistance profiles.
