Used as a key intermediate in the synthesis of nucleoside analogs, particularly in antiviral and anticancer drug development. Its protected sugar structure allows selective functionalization at specific positions, making it valuable in constructing modified ribose units for pharmaceuticals. Commonly employed in the preparation of purine and pyrimidine derivatives where stereochemical control is essential. Also utilized in oligonucleotide synthesis and carbohydrate chemistry research due to its stability and reactivity profile.
