Ethanedioic acid, bis(4-nitrophenyl) ester, also known as bis(4-nitrophenyl) oxalate or DNPO, is an organic compound with the chemical formula C14H8N2O8. It is a white crystalline solid that is soluble in organic solvents such as ethanol and acetone. Ethanedioic acid, bis(4-nitrophenyl) ester is primarily used as a reagent in the determination of carbonyl compounds, particularly in the DNP (Dinitrophenyl) derivatization method. In this method, the carbonyl group of the analyte reacts with DNPO to form a yellow-colored dinitrophenylhydrazone derivative, which can be quantified using UV-Vis spectroscopy. The formation of this derivative allows for the detection and quantification of carbonyl compounds in various samples, making DNPO a valuable tool in analytical chemistry.

5070-15-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5070-15-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,7 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5070-15:
(6*5)+(5*0)+(4*7)+(3*0)+(2*1)+(1*5)=65
65 % 10 = 5
So 5070-15-5 is a valid CAS Registry Number.
