Benzyloxycarbonyl-glutamine p-nitrophenyl ester (Z-Gln-pNO2) is a synthetic chemical compound that serves as a substrate for enzyme assays, particularly for proteases. It consists of a glutamine residue with a benzyloxycarbonyl (Z) protecting group and a p-nitrophenyl (pNO2) ester moiety. The Z group is used to protect the amino group of glutamine, preventing unwanted side reactions, while the p-nitrophenyl ester acts as a reporter group, allowing for the detection and quantification of enzyme activity. Upon enzymatic cleavage, the p-nitrophenyl group is released, and its absorbance at 410 nm can be measured, providing a quantitative assessment of protease activity. benzyloxycarbonyl-glutamine p-nitrophenyl ester is widely used in research and drug discovery to study the specificity, kinetics, and inhibition of proteases, which are essential for various biological processes and potential therapeutic targets.
The CAS Registry Mumber 3196-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 6 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3196-71: (6*3)+(5*1)+(4*9)+(3*6)+(2*7)+(1*1)=92 92 % 10 = 2 So 3196-71-2 is a valid CAS Registry Number.
