932-22-9, 4,5-Dichloro-3(2H)-pyridazinone is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
932-22-9, Step 1 3,4,5-Trichloropyridazine A stirred solution of 4,5-dichloro-2,3-dihydro-3-pyridazinone (15.00 g, 90.92 mmol) in POCl3 (100 mL) was refluxed for 1.5 h, then concentrated in vacuo. The residue was dissolved in CH2Cl2 (400 mL), washed with water (100 mL), dried over Na2SO4, filtered and concentrated to give 3,4,5-trichloropyridazine. M.S.(M+1):185.00.
The synthetic route of 932-22-9 has been constantly updated, and we look forward to future research findings.
