Used in the synthesis of complex carbohydrates and glycoconjugates, particularly in the development of glycosaminoglycan analogs and glycolipid derivatives. Serves as a protected glycosyl building block in solid-phase and solution-phase oligosaccharide synthesis. Its Cbz-protected aminoalkyl side chain allows for selective deprotection and further functionalization, enabling conjugation to proteins, lipids, or solid supports. Commonly applied in studies of carbohydrate-protein interactions, vaccine development, and enzymatic substrate design.
