From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Azole \Az"ole\, n. [From {Azote}.] (Org. Chem.)
     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.
