Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of hepatitis C virus (HCV) inhibitors. Its structure enables effective binding to viral enzymes, making it valuable in medicinal chemistry for designing drugs that target RNA-dependent RNA polymerase. Commonly employed in research settings to optimize potency and selectivity in nucleotide analogs. Also explored for its potential in oncology due to its ability to interfere with cellular replication pathways.
