Azole

[Sarah]

Any of a large class of compounds characterized by a five-membered ring which contains an atom of nitrogen and at least oneother noncarbon atom (nitrogen, oxygen, sulphur). The prefixes furo-,thio, and pyrro-are used to distinguish three subclasses of azoles,which may be regarded as derived respectively from furfuran,thiophene, and pyrrol by replacement of the CH group by nitrogen; as,furo-monazole. Names exactly analogous to those for the azines arealso used; as, oxazole, diazole, etc.
