Synthetic Route of 66346-83-6, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 66346-83-6, molcular formula is C5H4ClN3O, introducing its new discovery.
Compounds useful as schistosomicidal agents are cyclic alkylidenyl N-[6-(R3 R4 N)-4(or 5)-R5 -3-pyridazinyl]aminomethylenemalonates (I), where R3 R4 N is lower-tertiary-amino and R5 is hydrogen or lower-alkyl, are prepared by reacting 3-amino-6-(R3 R4 N)-4(or 5)-R5 -pyridazine (III) with cyclic alkylidenyl alpha-(lower-alkoxymethylene)malonate (IV) or by heating equimolar quantities of III, tri-(lower-alkyl) orthoformate and cyclic alkylidenyl malonate (V). Also shown is cyclic isopropylidenyl N-(6-methylamino-3-pyridazinyl)aminomethylenemalonate, a schistosomicidal agent, and its preparation. Also shown are schistosomicidal compositions comprising as active component a schistosomicidally effective cyclic alkylidenyl N-[6-(R3 R4 N)-4(or 5)-R5 -3-pyridazinyl]aminomethylenemalonate (I) or cyclic isopropylidenyl N-(6-methylamino-3-pyridazinyl)aminomethylenemalonate (II) or salt thereof and a method for the treatment of schistosomiasis which comprises administering to a host infected with schistosomes a schistosomicidally effective amount of said active component.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66346-83-6 is helpful to your research. Synthetic Route of 66346-83-6
