《A study on the ultraviolet spectroscopy of pyrrolecarboxylic acid esters》 was written by Rhee, Kyu Hyun; Han, In Sook. Category: esters-buliding-blocks And the article was included in Nonchong – Han’guk Saenghwal Kwahak Yonguwon in 1979. The article conveys some information:
The UV spectra of 32 pyrrolecarboxylic acid esters and 13 pyrrolecarboxylic acids were examined and their absorption wavelengths and absorption coefficients were classified according to π-π* or ET transition. The absorption maximum of N-arylpyrrole derivatives with electron-withdrawing substituents were linearly related according to the Hammett equation. The experimental part of the paper was very detailed, including the reaction process of Dimethyl 1H-pyrrole-2,3-dicarboxylate(cas: 2818-08-8Category: esters-buliding-blocks)
Dimethyl 1H-pyrrole-2,3-dicarboxylate(cas: 2818-08-8) belongs to pyrroles. Pyrroles are components of more complex macrocycles, including the porphyrinogens and products derived therefrom, including porphyrins of heme, the chlorins, bacteriochlorins, and chlorophylls. Porphobilinogen, a trisubstituted pyrrole, is the biosynthetic precursor to many natural products such as heme.Category: esters-buliding-blocks
