High-performance liquid chromatographic separation of bile acid pyrenacyl esters with cyclodextrin-containing mobile phase was written by Shimada, Kazutake;Komine, Yoshihiro;Mitamura, Kuniko. And the article was included in Journal of Chromatography, Biomedical Applications in 1991.COA of Formula: C18H11BrO The following contents are mentioned in the article:
Compared with conventional methods, inclusion chromatog. gives much more satisfactory separation of 1-bromoacetylpyrene-derivatized bile acids in a short time. The application of this method to the separation of glycine-conjugated bile acids in human bile is described. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5COA of Formula: C18H11BrO).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.COA of Formula: C18H11BrO
