Used as a glycosyl donor in carbohydrate synthesis, particularly in the preparation of complex oligosaccharides and glycoconjugates. Its acetyl protecting groups stabilize the molecule during reactions, while the anomeric amyl group allows for selective activation. Commonly employed in the synthesis of N-acetylglucosamine-containing structures found in biologically active molecules such as glycoproteins and bacterial cell wall components. Valuable in pharmaceutical research for developing glycosidase inhibitors and vaccine candidates.
