Azole
Pronunciation : Az"ole
Part of Speech : n. [From Azote.] (Org. Chem.)
Definition : Defn: Any of a large class of compounds characterized by a five- membered ring which contains an atom of nitrogen and at least one other 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 are also used; as, oxazole, diazole, etc.
