阿托伐他汀鈣的有關(guān)物質(zhì)的研究 已有1人參與
|
| 我最近做阿托伐他汀鈣片,分別用進口標(biāo)準(zhǔn)和歐洲標(biāo)準(zhǔn)做有關(guān)物質(zhì)的研究,結(jié)果這兩種方法雜質(zhì)B(非對應(yīng)異構(gòu)體)與主峰的分離度均不合格,分離度為0.8左右,我試著改變流動相比例,但效果一樣。我想問問大家做個這個產(chǎn)品嗎?遇到這種情況該怎么辦,是不是用的色譜柱不一樣。謝謝了 |

Atorvastatin Calcium. Because there is no existing USP monograph for this drug substance, a new monograph, based on validated methods of analysis, is proposed. The liquid chromatographic procedures in the tests for Related compounds and Assay are based on analyses performed with Zorbax Rx-C8 brand of L7 column. The typical retention time for atorvastatin peak is 26-34 minutes.The liquid chromatographic procedure in the test for Enantiomeric purity is based on analyses performed with Daicel Chiralpak AD brand of L51 column. The typical retention time for atorvastatin peak is about 44 minutes. |
