Geddes, Chris. D. published the artcileNew indolium and quinolinium dyes sensitive to aqueous halide ions at physiological concentrations, Application In Synthesis of 56523-59-2, the main research area is fluorescent dye indolium quinolinium preparation; halide ion physiol determination fluorescent indicator.
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.
Journal of Heterocyclic Chemistry published new progress about Cationic dyes. 56523-59-2 belongs to class bromides-buliding-blocks, name is 15-Bromopentadecanoic acid, and the molecular formula is C15H29BrO2, Application In Synthesis of 56523-59-2.
