Used as a glycosyl donor in carbohydrate chemistry, particularly in the synthesis of complex oligosaccharides and glycoconjugates. Its activated anomeric center allows for stereoselective glycosylation reactions, enabling the formation of α-glycosidic linkages with high efficiency. The benzoyl protecting groups stabilize the molecule during reactions and can be selectively removed to allow further functionalization. Commonly employed in the preparation of biologically active sugar derivatives, including those used in vaccine development and enzymatic studies.
