英文摘要Bupivacaine was found to be unstable during the accelerated storage condition(40 degrees C and 75% relative hu-midity), and two degradation impurities with the same protonated molecular ion were observed by high per-formance liquid chromatography-mass spectrometry (LC-MS). A semipreparative method was used to separate and purify the two impurities, and their structures were elucidated via comprehensive HR-MSMS and NMR spectroscopy analyses. Their stereo structures were characterized through single crystal X-ray diffraction. Meanwhile, an LC-MS method was developed and validated to quantify the two degradation impurities of bupivacaine. Chromatographic separation was performed on a C18 reversed-phase column (4.6 x 150 mm, 5 mu m) using an equivalent elution with water and methanol. The limits of quantitation for the two degradation im-purities (named RS1 and RS2) were 0.89 and 0.65 ng, respectively, and the average recoveries were in the range of 90 similar to 108% and relative standard deviations were less than 5.0%. The proposed LC-MS method can be used to control the quality of bupivacaine and its formulations. Data Availolity: Data will be made available on request.
