4-Nitrophenyl 2-(Acetamido)-2-deoxy-3-O-β-D-galactopyranosyl-α-D-galactopyranoside（Cat No.:R000309）is a glycoside compound used in biochemical research, particularly in enzyme activity assays. It consists of a galactopyranoside backbone with an acetamido group and a nitrophenyl group attached, where the nitrophenyl group serves as a chromogenic tag for detecting enzymatic cleavage. This compound is often used in assays to monitor the activity of enzymes like galactosidases, as the nitrophenyl group releases a yellow-colored product upon cleavage. Its structure makes it a valuable tool in carbohydrate chemistry, particularly for studying glycoside hydrolases and glycosyltransferases.
