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. Pyridine appears as a clear colorless to light yellow liquid with a penetrating nauseating odor. Vapors are heavier than air. Toxic by ingestion and inhalation.
