Used as a key intermediate in carbohydrate chemistry, particularly in the synthesis of complex oligosaccharides and glycosides. Its protected hydroxyl groups allow selective reactions at specific sites, making it valuable in the preparation of biologically active glycoconjugates, such as those found in vaccines and natural products. Commonly employed in glycosylation reactions where stereochemical control is essential. Also utilized in the pharmaceutical industry for constructing sugar moieties in antibiotic and antiviral agents.
