Abstract:
OBJECTIVE:To determine the related substance in cloperastine hydrochloride by HPLC.METHODS:The analysis was conducted on Agilent C18 column with the mobile phase consisted of 0.02 mol?L-1 KH2PO4-methanol(30∶70,triethlaminel 1.0 mL,adjusted to pH=3.5 with phosphoric acid) at a flow rate of 1.0 mL?min-1.The detection wavelength was 225 nm;the column temperature was set at room temperature,and the injection volume was 20 ?L.RESULTS:Effective segregation was achieved for the related substance from the chief chromatographic peak.The total peak area of the related substance in the sample was 0.13%~0.26% that of the main constituent of its reference substance(own control solution).CONCLUSION:The method is simple,accurate and specific,and applicable for the quality control of the related substance in cloperastine hydrochloride.
