Used as a key chiral intermediate in the synthesis of antiviral agents, particularly in the preparation of nucleoside analogs. Its fluorinated tetrahydrofuran structure enables enhanced metabolic stability and bioavailability in final drug compounds. Commonly employed in the development of RNA-targeting therapeutics, including treatments for hepatitis C and other viral infections. The presence of multiple functional groups allows selective modifications, making it valuable in medicinal chemistry for constructing complex, biologically active molecules.
