High Performance Liquid Chromatography (HPLC) Method of Imatinib mesylate.

Imatinib mesylate is effective in treating chronic myeloid leukemia and metastatic gastrointestinal stromal tumors. It is classified as a signal transduction inhibitor. It can be retained on an Obelisc R column, which has both positive and negative ion-pairs embedded in the stationary phase, allowing for the fine tuning and separation of a wide range of compounds with different ionic properties. Imatinib mesylate can be determined isocratically using a simple MS-compatible mobile phase of acetonitrile (ACN) and water with Ammonium Formate (AmFm) buffer and detected by UV at 270nm, ELSD, CAD or LC/MS.

Application Column

Obelisc R

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
