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, 21987-29-1, name is 4,4-Difluoropiperidine, introducing its new discovery. category: piperidines
Optimization of a series of aminomethyl ketone diamine H3R antagonists to reduce the brain exposure by lowering the pKa, led to molecules with improved pharmacokinetic properties. Compounds 9, 19, and 25 had high affinity for human H3R and demonstrated in vivo H3R functional activity in the rat dipsogenia model. Compound 9 displayed modest wake-promoting activity in the rat EEG/EMG model.
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 21987-29-1 is helpful to your research. category: piperidines
