| | 1(2H)-Phthalazinone Usage And Synthesis |
| Chemical Properties | Off-white to pale yellow crystalline powder | | Uses | Phthalazone is a remarkable scaffold in drug discovery. Also, functions as an oxidative metabolic pathway of lenvatinib mediated by aldehyde oxidase. | | Definition | ChEBI: Phthalazin-1(2H)-one is a member of phthalazines. | | General Description | Pale yellow crystals. Insoluble in water. | | Air & Water Reactions | Insoluble in water. | | Fire Hazard | Flash point data for 1(2H)-Phthalazinone are not available. 1(2H)-Phthalazinone is probably combustible. | | Purification Methods | Phthalazone crystallises from H2O or EtOH and sublimes in vacuo.
