Abstract
The following biologically active polyiodohalides of organic nitrogen bases were synthesized and studied: trimethylbenzylammonium, triethylbenzylammonium, and N-cetylpyridinium diiodochlorides; tetramethylammonium, tetrabutylammonium, and N-cetylpyridinium diiodobromides; and butylcholinium triiodide. A method for the identification of the above compounds was proposed based on the dependence of their thin-layer chromatographic mobility and IR, UV, and NMR spectrometric properties and on the nature of the organic cation and the structure of the polyiodide anion. Reversed-phase high-performance liquid chromatography in a 1 : 1 methanol–water mixture (pH 6.86) was used for determining the compounds under study. The developed procedure is characterized by high sensitivity (0.09–0.51 μg) at RSD of no worse than 10%.
