Used as an intermediate in the synthesis of antiviral drugs, particularly in the development of nucleoside analogs. These analogs are designed to inhibit viral replication by mimicking natural nucleosides, thereby interfering with viral RNA or DNA synthesis. It plays a key role in the production of medications targeting RNA viruses, including certain strains of hepatitis and coronaviruses. Its stereochemistry allows for high selectivity and efficacy in biological systems, making it valuable in pharmaceutical research and drug formulation.
