Used in the synthesis of complex carbohydrates and glycoconjugates, particularly in the preparation of oligosaccharide structures found in biological systems. Its protected functional groups allow selective deprotection and coupling in glycosylation reactions, making it valuable for constructing glycosidic linkages in a controlled manner. Commonly employed in the development of glycosyl donors for antigen synthesis, especially in vaccine research targeting bacterial or tumor-associated carbohydrate antigens. The Cbz-protected amino group enables further peptide coupling, facilitating the construction of glycopeptides. Widely applied in medicinal chemistry for studying cell recognition processes and designing glycomimetic drugs.
