823-58-5, 4-Amino-3,6-dichloropyridazine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 112.2: 6-chloro-3-hydrazinylpyridazin-4-amine To a stirred suspension of 3,6-dichloropyridazin-4-amine (Step 112.1) (1.49 g, 9.09 mmol) in EtOH (15 mL) was added hydrazine hydrate (11.04 mL, 227 mmol) and the resulting mixture was heated up and stirred at 100 C. for 3 hr. The reaction was cooled down to RT and concentrated under reduced pressure. The crude product was triturated with water (25 mL) to afford the title product (478 mg, 3 mmol, 33% yield) as yellow solid. tR: 0.24 min (LC-MS 2); ESI-MS: 160 [M+H]+ (LC-MS 2); ESI-MS: 158 [M-H]- (LC-MS 2).
As the paragraph descriping shows that 823-58-5 is playing an increasingly important role.
