Description
2-NITROPHENYL 4-O-BETA-D-XYLOPYRANOSYL-BETA-D-XYLOPYRANOSIDE is a white solid that serves as a substrate for measuring xylanase activity. Xylanases are enzymes that hydrolyze xylan into xylooligosaccharides, which have various applications in the food and feed industries.
Uses
Used in Food and Feed Industries:
2-NITROPHENYL 4-O-BETA-D-XYLOPYRANOSYL-BETA-D-XYLOPYRANOSIDE is used as a substrate for measuring xylanase activity, which is essential in the food and feed industries. Xylanases hydrolyze xylan into xylooligosaccharides, which can be utilized for various purposes, such as improving the nutritional value of feed, enhancing the texture of food products, and reducing the viscosity of certain industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 157956-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,5 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157956-98:
(8*1)+(7*5)+(6*7)+(5*9)+(4*5)+(3*6)+(2*9)+(1*8)=194
194 % 10 = 4
So 157956-98-4 is a valid CAS Registry Number.

Synthesis of 2- and 4-nitrophenyl β-glycosides of β-(1 → 4)-D-xylo-oligosaccharides of dp 2-4
Takeo,Ohguchi,Hasegawa,Kitamura
, p. 231 - 244 (2007/10/03)
2- and 4-Nitrophenyl β-D-xylopyranosides (4 and 5) were transformed, via dibutyltin oxide-mediated acylation, into the corresponding 2,3-di-O-benzoyl derivatives 11 and 15. Xylobiose and xylotriose were easily isolated by charcoal column chromatography from a commercially available material and converted into the di- and trisaccharide methyl 1-thio-β-glycosides 36 and 37. The 2- and 4-nitrophenyl β-glycosides of the β-(1 → 4)-D-xylo-oligosaccharides of dp 2-4 were synthesized by N-iodosuccinimide-silver triflate-promoted condensation using 11 and 15 as the glycosyl acceptors and ethyl 1-thio-β-D-xylopyranoside triacetate 16, 36, and 37 as the glycosyl donors. Also described are an improved preparation of 4 and 5, and the synthesis of 1-naphthyl β-D-xylopyranoside, as well as an alternative approach to the 2- and 4-nitrophenyl β-xylobiosides.
