With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6082-66-2,3,4,6-Trichloropyridazine,as a common compound, the synthetic route is as follows.
6082-66-2, Example 24A 3,6-dichloropyridazin-4-amine 3,4,6-Trichloropyridazine (25 g, 136 mmol) was added to 14. 8 N ammonium hydroxide (200 mL) in a 500 mL stainless steel pressure bottle. The mixture was stirred for 16 hours at 75 C. The mixture was cooled to ambient temperature, and 17 g (76%) of the title compound was collected by filtration as a solid. 1H NMR (400 MHz, DMSO-d6) delta ppm 7.16 (s, 2H), 6.82 (s, 1H); MS (ESI+) m/z 164 (M+H)+.
6082-66-2 3,4,6-Trichloropyridazine 95123, apyridazine compound, is more and more widely used in various fields.
