89898-86-2, 5-Nitrophthalazine is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
B. A solution of 5-nitro-phthalazine (0.175 g, 1 mmol) and SnCl2 (0.57 g, 3 mmol) in concentrated HCl (10 mL) is stirred at room temperature for 2 h. Ice is added to the solution. A solution of 25% NaOH is added to pH 14 (litmus). The solution is cooled for 18 h. The solution is filtered. Aqueous filtrate is extracted twice with EtOAc. EtOAc layers are combined, washed with water, brine, dried over Na2SO4, filtered and concentrated to give phthalazin-5-ylamine (0.050 g).
As the paragraph descriping shows that 89898-86-2 is playing an increasingly important role.
