development of linagliptin, five new process-related impurities were detected by high performance liquid chromatography (HPLC). All these impurities were identified, synthesized, and subsequently characterized by their respective spectral data (MS, HRMS, ¹H-NMR, (13)C-NMR and IR) as described in this article. The identification of these impurities should be useful for quality control and the validation
利格列汀是一种黄嘌呤衍生物,是用于治疗2型糖尿病的高效,选择性,长效和口服生物利用度DPP-4抑制剂。在利格列汀的工艺开发过程中,通过高效液相色谱(HPLC)检测到五种新的工艺相关杂质。如本文所述,对所有这些杂质进行鉴定,合成,然后通过它们各自的光谱数据(MS,HRMS,1 H-NMR,(13)C-NMR和IR)表征。这些杂质的鉴定对于质量控制和利那列汀生产中分析方法的验证应是有用的。
