摘要:

为了建立一种测定塞来昔布原料药及其制剂中塞来昔布磺酸甲酯和塞来昔布磺酸乙酯残留量的气相色谱-质谱(gas chromatography-mass spectrometry, GC-MS)分析方法,采用碘化钠衍生-顶空进样,将两杂质衍生成碘甲烷和碘乙烷,DB624毛细管色谱柱(60 m×0.25 mm, 1.4 μm)分离,氦气为载气,质谱检测器检测。塞来昔布磺酸甲酯和塞来昔布磺酸乙酯均在10~500 ng·mL-1浓度范围内线性关系良好;回收率在80.87%~106.52%,RSD小于10%;定量限均为10 ng·mL-1。所有塞来昔布样品中均未检测出塞来昔布磺酸甲酯和塞来昔布磺酸乙酯杂质。该方法简便准确,可用于塞来昔布中塞来昔布磺酸甲酯和塞来昔布磺酸乙酯2个磺酸酯类基因毒性杂质的检测。

Abstract:

A gas chromatography-mass spectrometry (GC-MS) method was developed for the determination of methyl celecoxib sulfonate and ethyl celecoxib sulfonate residues in celecoxib APIs and their formulations. The two impurities were derivatised into iodomethane and iodoethane by sodium iodide derivatisation with headspace injection, and separated on a DB-624 capillary column (60 m×0.25 mm, 1.4 μm), with helium as the carrier gas and detected by mass spectrometry detector. Both methyl celecoxib sulfonate and ethyl celecoxib sulfonate showed good linearity in the concentration range of 10~500 ng·mL-1; the recoveries were in the range of 80.87%~106.52% with the RSDs less than 10%; and the limits of quantification (LOQs) were both 10 ng·mL-1. Methyl celecoxib sulfonate and ethyl celecoxib sulfonate impurities were not detected in any of the celecoxib samples. The method is simple and accurate, which can be used for the detection of genotoxic impurities of two sulfonate esters, methyl celecoxib sulfonate and ethyl celecoxib sulfonate, in celecoxib.
