Used as a key intermediate in the synthesis of antiviral drugs, particularly nucleotide analogs for the treatment of Hepatitis C virus (HCV). It forms part of the structure for inhibitors targeting viral enzymes such as NS5B polymerase, helping to reduce viral replication in the body. Additionally, it is used in the development of nucleoside analogs requiring high specificity for biological targets. The structure featuring hydroxyl and carbamate groups enhances water solubility and molecular stability in biological systems, with the protected amine and free hydroxyl allowing for selective reactions in multi-step organic syntheses for drug development.
