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, 142374-19-4, name is tert-Butyl 4-(2-oxoethyl)piperidine-1-carboxylate, introducing its new discovery. Quality Control of: tert-Butyl 4-(2-oxoethyl)piperidine-1-carboxylate
A compound represented by the formula (1): (wherein X represents sulfur or oxygen; R1 and R2 each represents a group represented by the formula -Y3-Z, etc.; Y3 represents a single bond or (un)substituted alkylene; Y1 and Y2 each represents (un)substituted alkylene; Z represents hydrogen, an (un)saturated monocyclic heterocyclic group, etc.; M represents carboxy, etc.; Q represents o-phenylene, etc.; and A represents an (un)saturated monocyclic hydrocarbon group, etc.), a prodrug thereof, or a pharmaceutically acceptable salt of either. They are compounds having chymase inhibitory activity and useful as a therapeutic agent for hypertension, cardiac failure, etc.
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 142374-19-4 is helpful to your research. Quality Control of: tert-Butyl 4-(2-oxoethyl)piperidine-1-carboxylate
