In present work, an effective, innovative enantioselective synthetic strategy for the synthesis of
salmeterol xinafoate and its probable process-related impurities was reported. Seven pharmacopeia
specified impurities were synthesized and confirmed by FT-IR, mass, 1H & 13C NMR spectroscopy.
With respect to the corresponding retention factors, these contaminants were validated using the
available RP-HPLC method. These compounds can be used as a reference standard for the active
pharmaceutical ingredient manufactures and research organizations.
在这项研究中,报道了一种有效的、创新的对昔马特罗沙丁酸沙丁胺醇和其可能的与工艺相关的杂质进行对映选择性合成的策略。七种药典规定的杂质通过FT-IR、质谱、1H和13C NMR光谱进行了合成和确认。根据相应的保留因子,这些杂质使用现有的RP-HPLC方法进行了验证。这些化合物可以作为活性药物成分制造商和研究机构的参考标准。
