5788-58-9,5788-58-9, 4,5-Dibromopyridazin-3(2H)-one is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred suspension of 4,5-dibromopyridazmn-3(2H)-one (4.00 g, 15.8 mmol) in methanol (40 mL, 990 mmol), was added potassium carbonate (4.00 g, 28.9 mmol) and the mixture was stirred at 80t for 67 hours. The solvent was removed in vacuum. Water was added to the residue and acetic acid was added until acidic pH was reached. A solid precipitated and wascollected by filtration, washed with water, and dried to give 2.23 g (69 % yield) of the title compound as a crude product.LC-MS (Method 5): R = 0.57 mm; MS (ESIpos): mlz = 205 [M+H]
As the paragraph descriping shows that 5788-58-9 is playing an increasingly important role.
