摘要:

本文采用元素分析、紫外吸收光谱、红外吸收光谱、质谱和核磁共振(NMR)波谱(包含1H NMR、13C NMR、DEPT、1H-1H COSY、1H-13C HSQC和1H-13C HMBC)等方法对德拉沙星葡甲胺进行了结构分析,确证了德拉沙星葡甲胺的结构,分析了其IR谱图特征吸收峰对应的基团,对其1H和13C NMR信号进行了完整归属.并通过差示扫描量热法、热重分析及粉末X-射线衍射分析对德拉沙星葡甲胺的晶型进行了初步研究.

关键词: 德拉沙星葡甲胺, 核磁共振(NMR), 红外吸收光谱, 结构确证, 晶型

Abstract:

The structure of delafloxacin meglumine was analyzed by infrared absorption (IR), ultraviolet absorption (UV), nuclear magnetic resonance (1H NMR, 13C NMR, DEPT, 1H-1H COSY, 1H-13C HSQC and 1H-13C HMBC) spectroscopy, mass spectrometry and elemental analysis. The characteristic absorption peaks in the IR spectra were discussed. The 1H and 13C NMR signals of delafloxacin meglumine were assigned, and the two-dimensional signals were used to elucidate its structure. The crystal structure of delafloxacin meglumine was studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD).

Key words: delafloxacin meglumine, nuclear magnetic resonance (NMR), infrared absorption spectroscopy, structural elucidation, crystal structure
