WebJan 1, 2015 · Successive exchanges of the Na + for Cs + must be carried out, and one must use specially purified CsCl salt (reduced Rb impurity levels) to avoid the incorporation of Rb into the source [9, 10]. By heating the exchanged mordenite zeolite to 1050 °C, a phase transition from Na-M to Cs-M structure occurs. WebDuring the synthesis of the bulk drug Raloxifene hydrochloride, eight impurities were observed, four of which were found to be new. All of the impurities were detected using the gradient high performance liquid chromatographic (HPLC) method, whose area percentages ranged from 0.05 to 0.1%.
