3-Hydroxy-1-phenyl-1,2,4-triazole Usage And Synthesis
| Chemical Properties | light yellow crystal, mp284～286℃, soluble in dimethylformamide, slightly soluble in water. |
| Uses | 1-Phenyl-3-hydroxy-1,2,4-triazole is an intermediate of the organophosphorus insecticide triazophos. |
| Definition | ChEBI: 1-phenyl-1H-1,2,4-triazol-3-ol is a member of triazoles and a heteroaryl hydroxy compound. It is a tautomer of a 1-phenyl-1,2-dihydro-3H-1,2,4-triazol-3-one. It derives from a hydride of a 1-phenyl-1H-1,2,4-triazole. |
| Synthesis | 3-Hydroxy-1-phenyl-1,2,4-triazole was prepared by reacting Phenylhydrazine, urea and formic acid through condensation and cyclization reactions. |
