141-30-0, 3,6-Dichloropyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
2.70 kg (18.0 mol) of sodium iodide are added in portions at room temperature to a mixture of 5.0 l of water and 11.3 l of 57% aqueous hydroiodic acid (75.2 mol). 2.00 kg (13.4 mol) of 3,6-dichloropyridazine are subsequently added in portions to the solution held at 20 C. The reaction mixture is stirred at 20 C. for 18 hours. 10 l of tert-butyl methyl ether and 4 l of water are added to the reaction mixture. The organic phase is separated off and washed with water and aqueous sodium sulfite solution. The organic phase is concentrated, heptane is added, and the resultant solid is filtered off with suction and washed with heptane. The residue is dried in vacuo: 3-chloro-6-iodopyridazine as colourless leaf-shaped crystals; ESI 241.
141-30-0 3,6-Dichloropyridazine 67331, apyridazine compound, is more and more widely used in various.
