Used as a key intermediate in the synthesis of complex carbohydrates and glycoconjugates. Its multiple benzyl-protected hydroxyl groups allow selective deprotection and glycosylation reactions, making it valuable in the preparation of oligosaccharides for pharmaceutical research. Commonly employed in the development of vaccine candidates, particularly those targeting bacterial polysaccharide antigens. Also applied in the construction of glycosyl donors and acceptors in stereoselective glycosylation strategies.
