What is Pyridine?

Definition

ChEBI: Pyridine is an azaarene comprising a benzene core in which one -CH group is replaced by a nitrogen atom. It is the parent compound of the class pyridines. It has a role as an environmental contaminant. It is a mancude organic heteromonocyclic parent, a monocyclic heteroarene, an azaarene and a member of pyridines.
