Dimethyl 4-nitroheptanedioate is an organic compound with the chemical formula C9H15NO6. It is a colorless to pale yellow liquid with a molecular weight of 235.22 g/mol. This ester is derived from 4-nitroheptanedioic acid, where the two carboxylic acid groups are esterified with two methanol molecules. The compound is characterized by the presence of a nitro group (-NO2) attached to the fourth carbon atom in the heptane chain, which imparts specific chemical properties and reactivity. Dimethyl 4-nitroheptanedioate is used in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its versatile structure and functional groups. It is important to handle dimethyl 4-nitroheptanedioate with care, as the nitro group can be potentially explosive under certain conditions.

7766-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7766-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7766-83:
(6*7)+(5*7)+(4*6)+(3*6)+(2*8)+(1*3)=138
138 % 10 = 8
So 7766-83-8 is a valid CAS Registry Number.

Synthesis of γ-nitro aliphatic methyl esters via michael additions promoted by microwave irradiation

Escalante, Jaime,Francisco, D. Diaz-Coutino

experimental part, p. 1595 - 1604 (2010/03/24)

A simple and efficient protocol has been developed for the direct synthesis of γ-nitrobutyric acid methyl esters under microwave irradiation. This methodology reduces reaction times from days to minutes, compared to conventional conditions. Additionally, these conditions increased yields and provided cleaner reactions.

An improved coupling procedure for the Barton-Zard pyrrole synthesis

Bobal,Lightner

, p. 527 - 530 (2007/10/03)

An improved final step in the Barton-Zard pyrrole synthesis uses inexpensive potassium carbonate as base in the coupling-cyclization reaction of vic-nitro-acetates with isocyanides. In this modification the isolated yields of synthetically useful 2-carboalkoxypyrroles (1a,b and 3) and 2-(p-toluenesulfonyl)pyrroles (2a,b) consistently rise to the 78-89% range. Conversion of 2a to 5-(p-toluenesulfonyl)-2-pyrrolinone 4 is conveniently and directly achieved by reaction with 30% hydrogen peroxide in acetic acid, thus circumventing the commonly used two step procedure involving bromination followed by solvolysis.
