Benzyl N,N′-diacetyl-β-chitobioside is a biochemical reagent commonly used in glycoscience research. This field focuses on the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan synthesis and degradation enzymology, protein-glycan interactions, and the roles of glycans in biological systems. Glycoscience is closely linked to fundamental research, biomedicine, and biotechnology.
