1H-pyrrole-2,5-dicarboxylic acid dimethyl ester is an organic compound with the molecular formula C8H10N2O4. It is a derivative of 1H-pyrrole, a heterocyclic aromatic organic compound consisting of a pyrrole ring with two carboxylic acid groups at the 2nd and 5th positions. The dimethyl ester form indicates that the carboxylic acid groups are esterified with methanol, resulting in two methyl ester groups. 1H-pyrrole-2,5-dicarboxylic acid dimethyl ester is known for its potential applications in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its unique structure and reactivity. It is typically synthesized through chemical reactions involving pyrrole and its derivatives, and can be used as a building block in the preparation of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1757-29-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1757-29:
(6*1)+(5*7)+(4*5)+(3*7)+(2*2)+(1*9)=95
95 % 10 = 5
So 1757-29-5 is a valid CAS Registry Number.

Lithiations of 1-Trialkylsilylpyrroles: N to C Silyl Group Rearrangement

Chadwick, Derek J.,Hodgson, Simon T.

, p. 1833 - 1836 (2007/10/02)

The sites of metallation with alkyl-lithium reagents of 1-trimethylsilyl- and 1-triethylsilyl-pyrroles have been explored under a variety of conditions.With short reaction times, BunLi reacts with 1-trimethylsilylpyrrole in hexane predominantly at the 2-position though with ButLi in pentane the unusual 3-metallated product is preferred.During prolonged reaction of 1-trimethylsilyl- and 1-triethylsilyl-pyrroles with ButLi, the 2-monolithio- and the 2,4- and 2,5-dilithio-intermediates are formed, in which, unexpectedly, the silyl groups migrate to the pyrrole 2-position.Under conditions favouring enhanced ionicity, BunLi cleaves the N-SiMe3 bond in preference to ring metallation.
