4-Nitrophenyl 2-acetamido-2-deoxy-b-D-glucopyranoside

Chromogenic substrate for N-acetylglucosaminidase.

4-Nitrophenyl-N-acetyl-β-D-glucosaminide is a chromogenic substrate for N-acetyl-β-glucosaminidase. Hydrolysis of 4-nitrophenyl-N-acetyl-β-D-glucosaminide by N-acetyl-β-glucosaminidase releases 4-nitrophenol, which can be quantified by colorimetric detection at 405 nm as a measure of N-acetyl-β-glucosaminidase activity. It has been used to quantify the activity of N-acetyl-β-D-glucosaminidase in human serum and urine in parenterally fed patients.

4-nitrophenyl N-acetyl-beta-D-glucosaminide is an N-acetyl-beta-D-glucosaminide in which the anomeric hydroxy hydrogen is replaced by a 4-nitrophenyl group. It has a role as a chromogenic compound. It is a C-nitro compound and a N-acetyl-beta-D-glucosaminide. It derives from a 4-nitrophenol.
