Phthalazine Usage And Synthesis
  • Chemical PropertiesSLIGHTLY BROWN TO BEIGE CRYSTALLINE POWDER
  • UsesPhthalazine is a heterocyclic organic compound isomeric with quinoxaline, cinnoline and quinazoline. Aminophthalazine compounds serve as effective phosphodiesterase (PDE) inhibitors.
  • DefinitionChEBI: An azaarene that is the 2,3-diaza analogue of naphthalene. The parent of the class of phthalazines.
  • Synthesis Reference(s)Journal of Heterocyclic Chemistry, 2, p. 206, 1965 DOI: 10.1002/jhet.5570020219
  • Purification MethodsPhthalazine crystallises from diethyl ether or *benzene, and sublimes under a vacuum. The hydrochloride forms needles from EtOH with m 235-236o(dec) and the picrate has m 208-210o. [Armarego J Appl Chem 11 70 1961, Beilstein 23 H 174, 23 III/IV 1233.]
