And the article contained the following:
A novel imidazolium bonding method is proposed for the synthesis of hydrophilic interaction liquid chromatog. (HILIC) stationary phases. One obtained stationary phase (SilprAprImCl) was derived from direct reaction between N-(3-aminopropyl)-imidazole and 3-chloropropylated silica gel. Other two materials (SilprAprImBF4 and SilprAprImTf2N) were obtained from SilprAprImCl by ion exchange reaction, resp. FTIR spectroscopy and elemental anal. afforded the proofs of successful imidazolium immobilization and satisfied bonding efficiency. Various polar compounds such as saccharides, nucleosides, and nucleobases were used to evaluate the retention behaviors of these materials in HILIC mode. Different effects from mobile composition, column temperature, imidazolium unite and paired anions (Cl-, BF4-, and Tf2N-) in imidazolium were proved and discussed. Separation mechanism and the role of the imidazolium ions were also studied in mobile phases with different pH. Moreover, chromatog. stability was evaluated by consecutive injections. Finally, the reliability of these stationary phases was demonstrated by the separation of oligosaccharides in real fructooligosaccharides samples. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Application of 5036-48-6
