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.
