摘要: 目的:建立超高效液相色谱-质谱(UPLC-MS/MS)法检测盐酸决奈达隆原料药中3个遗传毒性杂质的残留量。方法:采用十八烷基硅烷键合硅胶 Waters ACQUITY UPLC BEH C18色谱柱(2.1 mm×50 mm×1.7 μm),柱温30 ℃,以0.1%的甲酸水溶液(A)-乙腈(B)为流动相,梯度洗脱,流速0.3 mL·min-1;通过质谱电喷雾正离子( ES + ) 模式电离、选择离子监测扫描模式(SIR)分别对3个遗传毒性杂质检测。结果:3个杂质分别在20.13~805.1 ng·mL-1(杂质Ⅰ)、62.15~776.9 ng·mL-1(杂质Ⅱ)、5.081~813.0 ng·mL-1(杂质Ⅲ)范围内线性关系均良好(r分别为1.000、1.000、0.999);各浓度下的平均回收率分别为 93.0%~99.4%(杂质Ⅰ)、83.5%~91.7%(杂质Ⅱ)、82.0%-92.9%(杂质Ⅲ)。结论:该方法操作简单,结果准确稳定,灵敏度高,线性范围较宽,满足样品测定的要求,为盐酸决奈达隆的质量控制提供方法支持。

Abstract: Objective: To establish a method for determining the residual amounts of three genotoxic impurities in dronedarone hydrochloride drug substance using UPLC-MS/MS. Methods: The analysis was performed on a Waters ACQUITY UPLC BEH C18 column (2.1 mm × 50 mm, 1.7 μm) at 30 ℃, with a mobile phase consisting of 0.1% formic acid aqueous solution (A) and acetonitrile (B) under gradient elution at a flow rate of 0.3 mL·min. The three genotoxic impurities were detected via electrospray positive ionization (ES+) mode and selected ion recording (SIR) scanning. Results: All three impurities exhibited excellent linearity within the ranges of 20.13-805.1 ng·mL-1 (Impurity Ⅰ), 62.15-776.9 ng·mL-1 (Impurity Ⅱ), and 5.081-813.0 ng·mL-1 (Impurity Ⅲ), with correlation coefficients (r) of 1.000、1.000 and 0.999. The average recoveries at different concentrations were 93.0%-99.4% (Impurity Ⅰ), 83.5%-91.7% (Impurity Ⅱ), and 82.0%-92.9% (Impurity Ⅲ). Conclusion: The method is simple to operate, with accurate and stable results, high sensitivity, and a wide linear range, meeting the requirements for sample determination. It provides methodological support for the quality control of dronedarone hydrochloride.
