Used as a glycosyl donor in carbohydrate chemistry, particularly in the synthesis of oligosaccharides and glycoconjugates. Its reactivity allows for the formation of glycosidic bonds with high stereoselectivity when coupled with appropriate glycosyl acceptors. Commonly employed in the preparation of N-acetylglucosamine-containing structures found in biologically important molecules such as glycoproteins and bacterial polysaccharides. The acetyl protecting groups stabilize the molecule during reactions and can be removed selectively after glycosylation to enable further chain elongation. Widely applied in pharmaceutical research for developing vaccine candidates and enzyme inhibitors.
