Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of nucleoside analogs. Its structure allows for selective modification of purine moieties, which is critical in designing drugs that inhibit viral replication. Commonly employed in research settings for modifying sugar-purine interactions to enhance metabolic stability and bioavailability in potential therapeutic compounds. Also utilized in the preparation of protected nucleoside building blocks for solid-phase oligonucleotide synthesis, aiding in the creation of antisense molecules and siRNA technologies.
