Used as a glycosyl donor in carbohydrate synthesis, particularly in the preparation of mannose-containing oligosaccharides. Its acetylated groups stabilize the molecule during reactions and help control stereochemistry during glycosylation. Commonly employed in the development of complex sugar structures for research in glycobiology, vaccine development, and synthesis of bioactive natural products. The compound is valuable in constructing antigenic fragments for immunological studies and in the design of glycoconjugate vaccines.
