A novel stability-indicating ultra performance liquid chromatographic (UPLC) method has been developed for quantitative determination of nilotinib hydrochloride in active pharmaceutical ingredients along with four impurities (imp-1, imp-2, imp-3 and imp-4). The method is applicable to the quantification of related compounds and assay of nilotinib hydrochloride drug. Efficient chromatographic separation was achieved on a Shim-pack XR-ODS II, 75 × 3.0 mm, 1.8-µm column with a gradient mobile phase combination. Quantification was carried at 260 nm at a flow rate of 0.6 mL min(-1). Stress degradation conditions were established for nilotinib hydrochloride by subjecting it to acid, base, oxidation, humidity, thermal and photolysis. The stress samples were assayed against a qualified reference standard and the mass balance was found close to 97.0%. The developed UPLC method was validated according to the present International Conference on Harmonisation guidelines for specificity, detection limit, quantitation limit, linearity, accuracy, precision, intermediate precision and robustness. The resolution between nilotinib hydrochloride and four potential impurities is found to be &gt;2.0. Regression analysis shows as r value (correlation coefficient) of &gt;0.999 for nilotinib hydrochloride and four potential impurities.
