pyrrol
Pyrrol is a five-membered heterocyclic organic compound with the chemical formula C4H5N. It features a fully unsaturated ring containing one nitrogen atom and four carbon atoms. Pyrrol is aromatic, meaning it possesses a planar ring structure with a delocalized pi electron system. This aromaticity contributes to its chemical stability.
The pyrrol ring is a fundamental building block in many biologically important molecules. For instance, it
Pyrrol itself is a colorless liquid that turns brown when exposed to air. It is soluble in
