Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of nucleoside analogs. Its structure allows selective modification at multiple sites, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. The iodine moiety enables further functionalization through cross-coupling reactions, while the silyl-protected hydroxymethyl group provides stability and controlled reactivity during multi-step syntheses. Commonly employed in research settings for the preparation of biologically active molecules targeting RNA and DNA viruses.
