p-Nitrophenyl α-D-xylopyranoside

Description:

p-Nitrophenyl α-D-xylopyranoside is a synthetic glycoside commonly used as a substrate in enzymatic assays, particularly for the detection of xylanase and other glycoside hydrolases. It features a p-nitrophenyl group, which serves as a chromogenic moiety, allowing for colorimetric detection upon hydrolysis. The α-D-xylopyranoside structure indicates that it is derived from D-xylose, a five-carbon sugar, and the α-anomeric configuration suggests that the glycosidic bond is formed at the anomeric carbon in the α position. This compound is typically a white to pale yellow crystalline solid, soluble in water and organic solvents, making it versatile for laboratory applications. Its hydrolysis releases p-nitrophenol, which can be quantified spectrophotometrically, providing a reliable method for measuring enzyme activity. Safety data indicates that it should be handled with care, as it may pose health risks if ingested or inhaled. Overall, p-Nitrophenyl α-D-xylopyranoside is a valuable tool in biochemical research and enzyme kinetics studies.
