目的:建立药物巴罗沙星的化学结构确证方法。方法:通过使用元素分析(EA)、热分析(TA)、X射线粉末衍射(XRD)、紫外吸收光谱(UV)、红外吸收光谱(IR)、核磁共振(NMR)以及质谱(MS)等分析手段对巴罗沙星进行了结构测定。结果:证实巴罗沙星的结构为1-环丙基-6-氟-1,4-二氢-8-甲氧基-4-氧代-7-(3-甲氨基-1-哌啶基)-3-喹啉羧酸二水合物。结论:方法测定结果准确全面,可为巴罗沙星的生产和鉴定提供较为全面的参考数据。
OBJECTIVE: To establish a chemical structure confirmation method for drug barofloxacin. Methods: The compounds were characterized by elemental analysis (EA), thermal analysis (TA), X-ray powder diffraction (XRD), ultraviolet absorption spectroscopy (UV), infrared absorption spectroscopy (IR), nuclear magnetic resonance (NMR) and mass spectrometry Means for the structure of the banroxacin determination. Results: The structure of the balofloxacin was confirmed to be 1-cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-4-oxo-7- (3-methylamino-1-piperidinyl) -3-quinolinecarboxylic acid dihydrate. Conclusion: The results of the method are accurate and comprehensive, which can provide more comprehensive reference data for the production and identification of barrosarcin.
