Tanaka, Shunitz published the artcileMigration behavior of niacin derivatives in capillary electrophoresis, Related Products of pyridine-derivatives, the publication is Journal of Chromatography A (1995), 718(1), 233-7, database is CAplus.
The migration behavior of niacin derivatives was investigated by capillary zone electrophoresis (CZE) and micellar electrokinetic chromatog. (MEKC). When the pH of the buffer solution is lower than the pKa of the pyridine ring in the niacin derivatives, they are pos. charged by protonation on the pyridine ring and migrate electrophoretically. The mobilities of niacin derivatives in CZE were controlled by the pH of the migrating buffer. Good separation of 13 niacin derivatives was achieved at pH 2.8. Further, to shorten the anal. time and to achieve a more complete separation, an investigation by MEKC using SDS micelles was performed. All 13 niacin derivatives were eluted within 30 min and a satisfactory separation was achieved.
