One of the major reasons is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level.Phthalazin-1(2H)-one, cas is 119-39-1,the phthalazine compound, introduce a new downstream synthesis route. 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.
119-39-1, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,119-39-1 ,Phthalazin-1(2H)-one, other downstream synthetic routes, hurry up and to see
