| Hazard Information | Back Directory | [Chemical Properties]
2-Phenyl-6-hydroxy-3-pyridazinone is a white powdery crystal with mp 268～272℃. It is easily soluble in dimethylformamide and 1-methyl-2-pyrrolidone, and poorly soluble in water, methanol, and benzene. It can form corresponding salts with various alkaline substances. It is stable in acidic, neutral, and alkaline solutions, and decomposes when exposed to strong oxidants. | [Uses]
3-HYDROXY-1-PHENYL-6-PYRIDAZONE is an intermediate of the organophosphorus insecticide benzopyrethrin. | [Definition]
ChEBI: 6-hydroxy-2-phenylpyridazin-3-one is a pyridazinone. | [Synthesis]
It was prepared by condensing phenylhydrazine with maleic anhydride to obtain 6-hydroxy-2-phenyl-3-pyridone. Dissolve phenylhydrazine hydrochloride in water, stirring and heating to 95 ℃, once added maleic anhydride, reflux 2h, cooling precipitation of li |
