Proceed as directed in the Optical Isomer, the retention time of the major peak of the test solution corresponds to that of the reference solution of Levofloxacin. 照光学异构体检查项下方法试验,供试品溶液主峰的保留时间应与对照品溶液左氧氟沙星峰的保留时间一致。
Study on the source of optical activity ⅱ. the effect of γ-radiation, β-radiation and electric discharge in ethanol on the formation of the optical isomer of 2, 3-butanediol 光学活性起源的研究&Ⅱ.γ射线、β射线、火花放电对生成2,3-丁二醇旋光异构体的影响
Separating and Determining Cypermethrin Optical Isomer with GC/ MS 用GC/MS分离鉴定氯氰菊酯光学异构体
Due to the configuration inversions of chiral carbon in the synthesis of side chain, we synthesized the corresponding optical isomer of doripenem for quality control. 由于在侧链的合成中,有手性碳原子发生了构型翻转,因此我们合成了一个相应的多利培南光学异构体,以利于质量控制。
