New indolium and quinolinium dyes sensitive to aqueous halide ions at physiological concentrations was written by Geddes, Chris. D.;Douglas, Peter;Moore, Christopher P.;Wear, Trevor J.;Egerton, Peter L.. And the article was included in Journal of Heterocyclic Chemistry in 1999.Computed Properties of C15H29BrO2 This article mentions the following:
New highly fluorescent dyes have been produced by the reaction of two heterocyclic nitrogen bases (6-methoxyquinoline and harmane) with 8-bromooctanoic acid, 11-bromoundecanoic acid, and 15-bromopentadecanoic acid. The bromide counter ions of the first six dyes were also replaced with the tetraphenylborate ion. Unlike the bases themselves, the quaternary salts are water soluble and have fluorescence characteristics independent of pH in the pH range 7-11. Both the fluorescence intensity and fluorescence lifetime of the 12 dyes are reduced in the presence of aqueous halide ions allowing halide concentrations to be determined accurately at physiol. levels. All the dyes have been characterized in terms of steady state fluorescence spectra and steady-state Stern-Volmer anal. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Computed Properties of C15H29BrO2).
15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Computed Properties of C15H29BrO2
