TITLE: | |
摘要: | 目的:建立测定二对甲苯磺酸缘生替尼原料药中有关物质的方法。方法:采用高效液相色谱法。色谱柱为Waters Symmetry C18,流动相为甲醇-0.01 mol/L乙酸铵溶液(梯度洗脱),流速为1.0 mL/min,检测波长为240 nm,柱温为40 ℃,进样量为10 μL。结果:在该色谱条件下,主成分峰与各杂质峰分离度均良好;杂质A、B、C和二对甲苯磺酸缘生替尼检测质量浓度线性范围均为0.25~2.0 μg/mL(r≥0.999 0),杂质A、B、C的定量限分别为0.5、0.5、2.5 ng;精密度、稳定性、重复性试验的RSD<1.0%;加样回收率分别为97.9%~102.6%、95.1%~107.7%、95.8%~107.5%,RSD分别为1.4%、4.2%、4.1%(n=9)。结论:该方法专属性好、操作简便,可用于二对甲苯磺酸缘生替尼原料药中有关物质的测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for the determination of related substances in yunsintinib ditosylate active pharmaceutical ingredient. METHODS: HPLC was performed on the column of Waters Symmetry C18 with mobile phase of methanol-0.01 mol/L ammonium acetate solution (gradient elution),flow rate was 1.0 mL/min, the detection wavelength was 240 nm, column temperature was 40 ℃,and injection volume was 10 μL. RESULTS: Under the chromatographic conditions, the main peaks and each impurity peak were well separated; The linear range of impurity A,B,C and yunsintinib ditosylaie were 0.25-2.0 μg/mL (r≥0.999 0);the quantification limits of impurity A, B and C were 0.5, 0.5 and 2.5 ng, respectively; RSDs of precision, stability and reproducibility tests were lower than 1.0%; recoveries were 97.9%-102.6% (RSD=1.4%,n=9),95.1%-107.7%(RSD=4.2%,n=9),95.8%-107.5%(RSD=4.1%,n=9), respectively. CONCLUSIONS: The method is specific and simple, and can be used for the determination of related substances in yunsintinib ditosylate active pharmaceutical ingredients. |
