Part of speech: adjective

Definitions

1. Relating to or derived from a five-membered aromatic ring structure containing nitrogen, especially characteristic of compounds with one nitrogen atom replacing a carbon atom in the ring; describing chemicals or molecular fragments displaying such a ring; pertaining to the chemical properties or reactions involving these nitrogenous rings
2. Concerning a class of organic compounds that include a pentagonal ring with a nitrogen atom, significant in biochemistry and synthetic chemistry; describing molecular entities or functional groups that embody this heterocyclic system; referring to substances or processes connected to this nitrogen-containing ring structure
3. Associated with or describing nitrogen-containing heterocycles based on a five-membered ring with one nitrogen atom; representing structural elements or compounds exhibiting this ring system; indicating chemical entities or behaviors that involve this type of aromatic ring framework

Etymology: The name begins with a colour. The Greek adjective "pyrrhos" meant flame-coloured or fiery red, and "pyrrole" took its name from it because a pine splint moistened with acid turns red when the compound is present. The name clings to a substance that gives no other hint of fire. The adjective is the chemical noun plus "-ic," the same ending found in "benzoic" and "acidic," which marks something as relating to or derived from a named substance. A pyrrolic compound is therefore one connected to the pyrrole ring, and the flame-red origin survives only in the root.

Synonyms: pyrrole-related, pyrrole-like
