physicochemical characterization of the process-related impurities associated with the synthesis of pemetrexed disodium was performed. The possibility of pemetrexed impurities forming has been mentioned in literature, but no study on their structure has been published yet. This paper describes the development of the synthesis methods for these compounds and discusses their structure elucidation on the basis
对与培美曲塞二钠合成相关的工艺相关杂质进行了物理化学表征。文献中已经提到形成培美曲塞杂质的可能性,但尚未发表对其结构的研究。本文描述了这些化合物的合成方法的发展,并讨论了基于二维 NMR 实验和 MS 数据的结构解析。这些杂质的鉴定应有助于培美曲塞二钠盐生产过程中的质量控制。
