Used in the synthesis of antiviral agents, particularly as an intermediate in the preparation of nucleoside analogs. It plays a key role in the development of prodrugs targeting RNA viruses, including hepatitis C and SARS-CoV-2. The compound's structure allows for selective modification of the sugar moiety, enhancing metabolic stability and cellular uptake when incorporated into active pharmaceutical ingredients. Its hydroxyl protection group facilitates controlled deprotection during multi-step synthesis, improving yield and purity in the final drug substance. Commonly employed in the manufacture of remdesivir-like therapeutics where precise stereochemistry and functional group compatibility are critical.
