Imidazo[1,2-b]pyridazines. I. Some 3-alkoxy-6-halo-2-phenyl-(and 4′-substituted phenyl)imidazo[1,2-b]pyridazines and 3-methoxy-2,6-diphenylimidazo[1,2-b]pyridazine was written by Barlin, Gordon B.. And the article was included in Australian Journal of Chemistry in 1986.Recommanded Product: 33097-39-1 This article mentions the following:
A series of the title imidazopyridazines I (R = F, Cl, Br, Ph; R1 = Me, Et; R2 = H, Cl, Br, MeO; R3 = R4 = H) have been prepared from the relevant pyridazin-3-amines and arylglyoxals, followed by O-alkylation of the corresponding imidazo[1,2-b]pyridazin-3(5H)-ones with diazoalkanes. 6-Chloro-3-methoxy-2-phenylimidazo[2,1-a]phthalazine I (R = Cl; R1 = Me; R2 = H; R3R4 = CH:CHCH:CH) was prepared similarly. In the experiment, the researchers used many compounds, for example, 3,6-Difluoropyridazine (cas: 33097-39-1Recommanded Product: 33097-39-1).
3,6-Difluoropyridazine (cas: 33097-39-1) belongs to pyridazine derivatives. Pyridazine and phthalazine have quite different spectroscopic properties compared with their isomers, pyrazine and quinoxaline. Specifically, the pyridazine moiety is an important structural feature of various pharmacologically important compounds with activities like antimicrobial, analgesic, anti-inflammatory, antiplatelet, anticancer, antisecretory, antiulcer, antidepressant, cardiotonic, vasodilator, antiarrhythmic, and hypocholesterolaemic.Recommanded Product: 33097-39-1
