Electric Literature of 54450-20-3, 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, 54450-20-3, molcular formula is C8H5BrO2, introducing its new discovery.
A class of substituted azetidine, pyrrolidine and piperidine derivatives of Formula I are selective agonists of 5-HT 1 -like receptors, being potent agonists of the human 5-HT 1Dalpha receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT 1Dalpha receptor subtype relative to the 5-HT 1Dbeta subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT 1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT 1D receptor agonists.

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 54450-20-3 is helpful to your research. Electric Literature of 54450-20-3
