Attempts to synthesize impurities of Gastro prokinetic drug tegaserod maleate, Three unknown impurities in tegaserod maleate bulk drug at level below 0.1% (ranging from 0.05 to 0.1 %) were detected by simple reverse phase high performance liquid chromatography (HPLC). These impurities were preliminarily identified with LCMS and by knowing the mass of the impurities, different experiments were conducted
尝试合成促胃动力药马来酸替加色罗的杂质,通过简单的反相高效液相色谱 (HPLC) 检测到马来酸替加色罗原料药中浓度低于 0.1%(范围为 0.05 至 0.1%)的三种未知杂质。这些杂质通过LCMS初步鉴定,并通过了解杂质的质量,进行不同的实验,最终合成并表征为未知杂质
