A rapid, precise, and selective reverse-phase high-performance liquid chromatography (RP-HPLC) method was established and validated for the analysis of QTPF (QUETIAPINE FUMERATE) pure drug as well as commercial formulation.  This RP-HPLC approach is designed for the regular determination of QTPF in both laboratory-prepared mixtures and combined pharmaceutical formulations. The separation process utilized an INERTSIL C-18 ODS column (physical dimension 250×4.6mm, 5µm particle size), employing a mobile phase of methanol and ammonium acetate (30 Mm) in a 95:5 ratio, with a flow rate of 1ml/min. The detection of QTPF was achieved using UV spectrophotometry method.  QTPF was found to be highly soluble in ACN and methanol in ratio of 70:30, and its wavelength was found to be 252nm. Retention time of QTPF was found to be 3.4 min.  The LOD and LOQ values were found to be 0.0001 (µg/ml) and 0.0003, (µg/ml) respectively. In the linearity curve of 2 to 64(µg/ml) of sample, correlation coefficient R² is seen to be 0.9992. The system suitability parameters such as theoretical plates and tailing factor were found to be 1.99 and 1.30, respectively, and RSD was found to be 1.45.
