In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 932-22-9, name is 4,5-Dichloro-3(2H)-pyridazinone, introducing its new discovery. category: pyridazine
The invention relates to novel processes for the preparation of 5-chloro-4-{3-[N-[2-(3,4-dimethoxyphenyl)-ethyl]-N-methylamino]-propylamino-3(2H) pyridazinone of formula (I) and the pharmaceutically acceptable acid addition salts thereof. An important feature of the invention is using 3,4,5-trichloropyridazone as starting substance of the synthesis.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 932-22-9 is helpful to your research. category: pyridazine
