N-Carbonyl-glycin-<4-nitro-phenylester>, also known as 4-nitrophenyl glycinate, is an organic compound with the chemical formula C9H8N2O4. It is a derivative of glycine, an amino acid, and 4-nitrophenol, a nitrophenol compound. This molecule is characterized by a glycine moiety connected to a 4-nitrophenyl ester group, which is formed by the esterification of the carboxylic acid group of glycine with the hydroxyl group of 4-nitrophenol. The compound is often used as a substrate in enzymatic reactions, particularly in the study of enzymes like proteases and esterases, due to its ability to undergo hydrolysis under the influence of these enzymes. The 4-nitrophenyl group serves as a chromophore, allowing for the colorimetric detection of the reaction progress, which is useful in assays and research.
The CAS Registry Mumber 7352-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 2 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7352-43: (6*7)+(5*3)+(4*5)+(3*2)+(2*4)+(1*3)=94 94 % 10 = 4 So 7352-43-4 is a valid CAS Registry Number.
