19406-11-2 Usage
General Description
1H-Pyrrole-3-carboxylic acid, 1,2-dimethyl-, ethyl ester is a chemical compound that belongs to the class of organic compounds known as pyrrole carboxylic acids and derivatives. The molecular structure of this chemical includes a pyrrole ring, which is a five-membered aromatic ring with one nitrogen atom, and a carboxylic acid ester group. The unique aspect of this particular compound is the presence of 1,2-dimethyl substitutions on the pyrrole ring and an ethyl ester group attached to the carboxylic acid, which likely impacts its chemical properties such as reactivity and solubility. 1H-Pyrrole-3-carboxylic acid, 1,2-dimethyl-, ethyl ester could play a role in various chemical reactions, although its specific applications or biological activities are not well-known.
Check Digit Verification of cas no
The CAS Registry Mumber 19406-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19406-11:
(7*1)+(6*9)+(5*4)+(4*0)+(3*6)+(2*1)+(1*1)=102
102 % 10 = 2
So 19406-11-2 is a valid CAS Registry Number.

Reactions of Carbethoxycarbene with Enaminones. Formation of Unexpected Pyrroles
Augusti, Rodinei,Eberlin, Marcos N.,Kascheres, Concetta
, p. 1355 - 1358 (2007/10/03)
The reactions of carbethoxycarbene (:CH2-CO2Et, 2) with several acyclic enaminones (RCOCH=CR1NHR2, 3) lead to the unexpected formation of 2-Me, 3-CO2Et, 4-H, 5-R1-pyrroles 4.Structural variations of the enaminones show that the structural fragments C(3)-CO2Et and C(2)-Me are provided by 2 and that the fragment C(5)-R1NHR2 originates from the enaminones 3, while the RCO group from 3 is eliminated during the course of reaction.Reactions with cyclic and nitrogen-hindered enaminones do not lead to pyrrole formation but occur by simple insertion of 2 to the Cα-H bond.
