Used as an intermediate in the synthesis of antiviral medications, particularly in the development of nucleoside analogs. It plays a role in modifying molecular structures to enhance bioavailability and metabolic stability. Commonly employed in pharmaceutical research for prodrug design, where it helps improve cellular uptake and targeted delivery. Also utilized in the preparation of cyclopropane-containing compounds that show activity against certain RNA viruses. Its structure supports conformational rigidity, which is beneficial in drug design for increasing potency and selectivity.
