High-performance liquid chromatography/mass spectrometer (HPLC/MS) was used to identify and structurally characterize the modified nucleoside cladribine (2-chloro-2'-deoxy-beta-adenosine) and 13 synthesis-related byproducts in bulk drug. Confirmation of compound identity was accomplished by spectral analysis (1H and 13C NMR spectroscopy, mass spectrometry, and UV absorption spectroscopy) of the related
高效液相色谱/质谱仪(HPLC / MS)用于鉴定和结构表征散装药物中修饰的核苷克拉屈滨(2-氯-2'-脱氧-β-腺苷)和13种与合成相关的副产物。通过从原料药的粗混合物中分离出的相关化合物进行光谱分析(1H和13C NMR光谱,质谱和UV吸收光谱),并通过使用真实标准品进行加标实验,可以确认化合物的身份。在线质谱分析(即LC / MS)的使用可增强UV吸收光谱,从而可以快速鉴定许多目标化合物。
