SLIGHTLY BROWN TO BEIGE CRYSTALLINE POWDER
Uses
Phthalazine is a heterocyclic organic compound isomeric with quinoxaline, cinnoline and quinazoline. Aminophthalazine compounds serve as effective phosphodiesterase (PDE) inhibitors.
Definition
ChEBI: Phthalazine is an azaarene that is the 2,3-diaza analogue of naphthalene. The parent of the class of phthalazines. It is a mancude organic heterobicyclic parent, a member of phthalazines, an azaarene and an ortho-fused heteroarene.
Purification Methods
Phthalazine 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.]
