摘要: 对拉呋替丁的氢谱(1H NMR)、碳谱(13C NMR,DEPT)、异核多键相关谱(HMBC)予以解析并进行了报道,对其所有的1H NMR和13C NMR谱信号进行了归属;讨论了红外特征吸收,热差和热重分析;质谱的裂解途径和离子特征也与拉呋替丁的分子结构相符. 

Abstract: Mass spectrum and one-dimensional (1H and 13C ) and two-dimensional (heteronuclear multiple-bond coherence, HMBC) NMR spectra of lafutidine were reported and interpreted. The 1H and 13C chemical shifts were assigned. The spectroscopic characteristics of the compound were discussed in detail and found to be consistent with its structure known previously.

Key words: NMR, mass spectrometry, chemical shift assignment, lafutidine
