Abstract: | Objective:To establish a method for determination of the genotoxic impurities of NDMA and NDEA in the active pharmaceutical ingredient of dacarbazine by UHPLC-APCI-MS/MS.Methods:The test was performed in Kinetex F5 column(3 mm×100 mm,2.6μm)under the gradient elution of 0.1%formic acid solution(mobile phase A)and methanol(mobile phase B).The flow rate was 0.4 mL·min-1,and the column temperature was 40℃.The ionization mode of mass spectrometry was APCI with positive ion mode,and determination was conducted in MRM scan mode by the external standard method.The ion pairs were m/z 75.1/58.0 for NDMA and m/z 103.0/47.0 for NDEA.Results:The established method for the separation and analysis of NDMA and NDEA was validated.The linear relationship in the linear range was good(r>0.990).The limits of detection were 0.03030 and 0.003787 ng·mL-1,respectively.The precision and stability results met the criteria,the recovery rate was 97%-115%,and all the relative standard deviations were less than 5%.Conclusion:The established method is accurate,rapid,sensitive and specific.It can be used for the quality control of the genotoxic impurities of NDMA and NDEA in API of Dacarbazine. |
