Pyrrole is a heterocyclic, aromatic, organic compound, a five-membered ring with the formula C 4 H 4 NH. [3] It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N -methylpyrrole, C 4 H 4 NCH 3 .

The epsilon-amino groups of lysyl residues react with 2,5-hexanedione forming pyrrole adducts, followed by pyrrole-mediated protein crosslinking. Both reaction steps have been proposed as mechanisms causing neurofilament accumulation and acceleration of transport.

Pyrrole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of four carbon atoms and one nitrogen atom. The simplest member of the pyrrole family is pyrrole itself, a compound with molecular formula C4H5N.

Pyrrole is very much less basic than secondary amines but much more acidic. Pyrrole is, however, still a very weak acid (p K a = 17.5). The nitrogen-bound proton can be abstracted from pyrrole by the use of strong bases such as sodium amide …

Pyrrole is a five-membered heterocyclic organic compound having the general formula C4H4NH. It consists of two pi bonds and one lone pair of electrons contributing to a pi system. Thus it has six pi electrons. It obeys all the parameters of Huckel’s Rule. Therefore, it …

Pyrrole. Pyrrole is a five-membered heterocyclic ring which has 5 p orbitals and six pi electrons contributing to its aromaticity. Each carbon in pyrrole contributes one p orbital and pi electron. The nitrogen in pyrrole contributes two pi electrons by becoming sp 2 hybridized and placing its lone pair electrons into a p orbital. The ...

Pyrrole is a heterocyclic aromatic compound that can undergo electrophilic aromatic substitution. Application. Pyrrole was used in the electropolymerisation of macroporous conducting polymer films. It was also used to study the hydrogen-bond mediated coupling of 1,2,3-triazole to pyrrole. Safety Information ...

Apr 22, 2024 · Apart from its interest as an aromatic system, the pyrrole is biologically important because its structure is part of the heme group, chlorophyll and other natural products related to vitamin B12 and bile pigments.
