2,4-Dinitrophenyl 2-deoxy-2-fluoro-b-xylobioside

2,4-Dinitrophenyl 2-deoxy-2-fluoro-4-O-b-D-xylopyranosyl-b-D-xylopyranoside

2,4-Dinitrophenyl 2-deoxy-2-fluoro-beta-xylobioside, also known as DNFPX, is a substrate to study the activity of glycosidases. It is a derivative of xylobiose, which is a disaccharide composed of two xylose units. The 2-deoxy-2-fluoro modification on one of the xylose units makes the compound resistant to further hydrolysis by the enzyme, allowing it to be used as a reporter of enzyme activity. The 2,4-Dinitrophenyl group is used as a chromogenic group that enables rapid detection and measurement of the enzyme activity that can be quantitatively measured by monitoring the appearance of the yellow 2,4-dinitrophenyl group when cleavage of the glycosidic bond.
