Abstract
A hydrophilic interaction chromatography (HILIC) method has been developed and validated as a secondary or orthogonal method complementary to a reversed-phase HPLC (RP-HPLC) method for quantitation of a polar active pharmaceutical ingredient and its three degradation products. The HILIC method uses a diol column and a mobile phase consisting of acetonitrile/water and ammonium chloride. The compounds of interest show significant differences in retention behaviors with the two very different chromatographic systems, which are desired in developing orthogonal methods. The HILIC method is validated and has met all validation acceptance criteria for the support of drug development activities.
