And the article was included in Shikizai Kyokaishi in 1989.Computed Properties of C18H11BrO The following contents are mentioned in the article:
The title dye (I) was synthesized by the reaction of rhamnolipid B K salt with 1-(bromacetyl)pyrene in the presence of 18-crown-6 as a catalyst. I was evaluated as a fluorescent probe for membrane fluidity or potential. Four kinds of fluorescent patterns were clearly observed in various solvents, micelles and liposomes which well reflected the difference in location and microenvironment around the I mols. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Computed Properties of C18H11BrO).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. 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.Computed Properties of C18H11BrO
