1H-Pyrrole-3,4-dicarboxylic acid, 2,5-bis[3-(trifluoromethyl)phenyl]-, diethyl ester is a complex organic compound with the molecular formula C22H16F6N2O4. It is a derivative of 1H-pyrrole-3,4-dicarboxylic acid, featuring two trifluoromethylphenyl groups attached to the pyrrole ring at the 2 and 5 positions. The diethyl ester functional group is present, indicating that the carboxylic acid groups are esterified with ethanol. 1H-Pyrrole-3,4-dicarboxylic acid, 2,5-bis[3-(trifluoromethyl)phenyl]-, diethyl ester is characterized by its unique structure, which includes a pyrrole ring, fluorinated aryl groups, and an ester linkage. It is likely to be used in the synthesis of more complex molecules or as an intermediate in organic chemistry, potentially in pharmaceuticals or materials science, due to its specific structural features.

Check Digit Verification of cas no

The CAS Registry Mumber 92844-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,4 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92844-44:
(7*9)+(6*2)+(5*8)+(4*4)+(3*4)+(2*4)+(1*4)=155
155 % 10 = 5
So 92844-44-5 is a valid CAS Registry Number.

Synthesis of 2H-1,4-Thiazine-2,6-dicarboxylates and Their Conversion to 3,4-Pyrroledicarboxylates via Sulfur Extrusion

Lee, Len F.,Howe, Robert K.

, p. 4780 - 4783 (1984)

The reactions of 3-aminocinnamates 1c,d with S2Cl2 provided 2,5-diaryl-3,4-pyrroledicarboxylates 7c,d in 36-52percent yields whereas the reactions of 3-(perfluoroalkyl)-3-aminoacrylates 1e-h with S2Cl2 or SCl2 gave 3,5-bis(perfluoroalkyl)-2H-1,4-thiazine-

Tandem Synthesis of Tetrasubstituted NH Pyrroles from Simple Nitriles

Kim, Hyeongsu,Xuan, Zi,Hyun Kim, Ju

supporting information, p. 3336 - 3340 (2021/09/09)

An efficient tandem route to obtain tetrasubstituted NH pyrroles in a one-pot manner has been developed, staring from simple nitriles, ethyl bromoacetates, and zinc. This reaction involves oxidative dimerization of the zinc bromide complex of β-enaminoesters using cerium ammonium nitrate (CAN) as an oxidant, affording 2,3,4,5-tetrasubstituted pyrroles in yields up to 91%.
