Catalog No: A10GD-4148
Cas No: 120583-41-7
Properties: Mol Formula: C18H24ClNO13, Mol Weight: 497.8
IUPAC Name: (2S,3R,4S,5R,6R)-2-[(2R,3S,4R,5R,6S)-6-(2-chloro-4-nitrophenoxy)-4,5-dihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol
Synonym: 2-Chloro-4-nitrophenyl b-D-lactoside, (2S,3R,4S,5R,6R)-2-[(2R,3S,4R,5R,6S)-6-(2-chloro-4-nitrophenoxy)-4,5-dihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol, b-D-Glucopyranoside, 2-chloro-4-nitrophenyl 4-O-b-D-galactopyranosyl-
2-Chloro-4-nitrophenyl b-D-galactopyranoside is a chromogenic enzyme substrate used to study the activity of beta-lactoside. It produces a yellow color when cleaved by the enzyme, making it a useful tool in enzyme assays and screening experiments.
Highly sensitive lactosidase, yellow coloured probe that releases the product 2-chloro-4-nitrophenol (CNP). Can be monitored spectrophotometrically at 405 nm. The rate of formation of 2-chloro-4-nitrophenol is directly proportional to the lactosidase activity in the sample. The pKa of CNP is approximately 5.5.
