HPLC of Formula: 40020-05-1On October 31, 1989 ,《Organic azides in heterocyclic synthesis. Part 9. Ring closure of 4-azido-3-phenylpyridazines to pyridazino[4,3-b]indoles》 was published in Synthesis. The article was written by Stadlbauer, W.; Pfaffenschlager, A.; Kappe, T.. The article contains the following contents:
The cyclization of 4-azido-3-phenylpyridazines I (R = Cl, OH) and 7-azido-6-phenyltetrazolo[1,5-b]pyridazine II by heating with strong acids like MeSO3H affords 5H-pyridazino[4,3-b]indoles III or 10H-tetrazolo[1′,5′:1,6]pyridazino[4,3-b]indole IV, resp., whereas conventional photochem. and thermolytic methods fail. In the experiment, the researchers used many compounds, for example, 4,6-Dichloro-3-phenylpyridazine(cas: 40020-05-1HPLC of Formula: 40020-05-1)
4,6-Dichloro-3-phenylpyridazine(cas: 40020-05-1) belongs to pyridazine. The pyridazine moiety is an important structural feature of various pharmacologically important compounds with activities like antimicrobial, antiplatelet, anticancer, antisecretory, analgesic, anti-inflammatory, antiulcer, antidepressant, neuroleptic, sedative-hypnotic, anticonvulsant, immunosuppressant, cardiotonic, vasodilator, antiarrhythmic, and hypocholesterolaemic.
