Used as a key intermediate in the synthesis of complex carbohydrates and glycoconjugates, particularly in the preparation of oligosaccharides found in biological systems. Its protected functional groups allow selective glycosylation reactions, making it valuable in constructing glycosidic bonds with high stereocontrol. Commonly employed in the development of glycosaminoglycan fragments, vaccine candidates, and enzyme inhibitors. The benzylidene and acetamido groups provide stability and regioselectivity during chain elongation in automated or stepwise oligosaccharide assembly.
