The phthalazine compound, name is Phthalazin-1(2H)-one,cas is 119-39-1, mainly used in chemical industry, its synthesis route is as follows.,119-39-1
1b) 1-Chlorophthalazine hydrochloride A suspension of 50 g (342 mmol) phthalazone, 1370 ml acetonitrile, 66 ml (0.72 mol) POCl3 and 85 ml 4 N HCl in dioxane is stirred for 8 h at 50 C. The resulting solution is cooled to RT, evaporated to a volume of about 0.8 l and diluted with 1.2 l DIPE. Filtration and washing with DIPE yield the title compound: FAB-MS (M+H)+=165/167.
As the rapid development of chemical substances, we look forward to future research findings about 119-39-1
