  • Applications

    Xylobiose (CAS 6860-47-5) is a disaccharide composed of two xylose units. In industry, it is commonly used as an intermediate and building block for the synthesis of xylooligosaccharides and xylose-containing polymers; it also serves as a substrate for glycosidase enzymes and for studies of transglycosylation and enzyme development. It is evaluated as a potential prebiotic component in food formulations and as a reference material for carbohydrate analysis and chromatography methods. Additionally, xylobiose can be considered a feedstock for bioconversion to xylose or other bio-based chemicals, supporting bioprocess and industrial applications.
