Synthetic Route of 453-20-3, 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, 453-20-3, molcular formula is C4H8O2, introducing its new discovery.
Compounds, pyridine N-oxides, and pharmaceutically acceptable salts of formula (I) are useful as inhibitors of the phosphodiesterase 4 (PDE4) enzyme and for preventing and/ or treating diseases of the respiratory tract characterized by airway obstruction, such as asthma or COPD.
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 453-20-3 is helpful to your research. Synthetic Route of 453-20-3
