1,3-Benzenedicarboxylic acid, 2-hydroxy-5-nitro-, diethyl ester is a complex organic compound with the chemical formula C12H13NO8. It is derived from 1,3-benzenedicarboxylic acid, which has two carboxylic acid groups attached to a benzene ring. In this specific compound, the 2-position on the benzene ring is substituted with a hydroxyl group (-OH), and the 5-position is substituted with a nitro group (-NO2). The diethyl ester indicates that the two carboxylic acid groups are each esterified with an ethyl group (-CH2CH3). 1,3-Benzenedicarboxylic acid, 2-hydroxy-5-nitro-, diethyl ester is known for its potential applications in the synthesis of pharmaceuticals and other organic compounds, and it is characterized by its unique chemical structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 72078-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,7 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72078-90:
(7*7)+(6*2)+(5*0)+(4*7)+(3*8)+(2*9)+(1*0)=131
131 % 10 = 1
So 72078-90-1 is a valid CAS Registry Number.

A convenient method for synthesizing modified 4-nitrophenols

Nakaike, Yumi,Kamijo, Yoshio,Mori, Satoshi,Tamura, Mina,Nishiwaki, Nagatoshi,Ariga, Masahiro

, p. 10169 - 10171 (2007/10/03)

β-Nitroenamine having a formyl group behaves as the synthetic equivalent of unstable nitromalonaldehyde upon treatment with ketones under basic conditions and leads to 2,6-disubstituted 4-nitrophenols. The present method is safer than the conventional one using sodium nitromalonaldehyde and enables the preparation of hitherto unknown nitrophenols.

Nucleophilic Reaction upon Electron-deficient Pyridone Derivatives. IV. Ring Transformation of 1-Substituted 3,5-Dinitro-2-pyridones with Ketones in the Presence of Amines

Matsumura, Eizo,Tohda, Yasuo,Ariga, Masahiro

, p. 2174 - 2180 (2007/10/02)

Ring transformation of 1-substituted 3,5-dinitro-2-pyridones with 1,3-disubstituted acetones in the presence of secondary or primary amines gave p-nitroaniline derivatives and N-substituted 2-nitroacetamide.Two types of enamine intermediates, 2-azabicyclononene derivatives and N-substituted 2-(5-amino-2-nitro-2,4-cyclohexadienyl)-2-nitroacetamides were isolated and characterized.The course of the base-catalyzed reaction is interpreted.
