A triazole (Htrz) refers to any of the heterocyclic compounds with molecular formula C2H3N3, having a five-membered ring of two carbon atoms and three nitrogen atoms. There are two sets of isomers that differ in the relative positions of the three nitrogen atoms. Each of these has two tautomers that differ by which nitrogen has a hydrogen bonded to it: *1,2,3-Triazole 1H-1,2,3-Triazole Structural FormulaV.1.svg|1''H''-1,2,3-Triazole 2H-1,2,3-Triazole Structural FormulaV.1.svg|2''H''-1,2,3-Triazole *1,2,4-Triazole 1H-1,2,4-Triazole Structural FormulaV.1.svg|1''H''-1,2,4-Triazole 4H-1,2,4-Triazole Structural FormulaV.1.svg|4''H''-1,2,4-Triazole ==Derivatives== The triazole antifungal drugs include fluconazole, isavuconazole, itraconazole, voriconazole, pramiconazole, ravuconazole, and posaconazole. The triazole plant protection fungicides include epoxiconazole, triadimenol, propiconazole, prothioconazole, metconazole, cyproconazole, tebuconazole, flusilazole and paclobutrazol. Benzotriazole is used in chemical photography as a restrainer and fog-suppressant. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「triazole」の詳細全文を読む スポンサード リンク
