| titleOfInvention | A kind of calcitriol compound, its preparation method, separation method and use |
| abstract | The invention discloses a calcitriol compound, its preparation method, separation method and application. The preparation method includes the following steps: degrading calcitriol with an alkali at 60-80° C. in a solvent and in the dark. The separation method of the invention can effectively separate the related substances of the calcitriol raw material medicine, and the method has strong specificity, high sensitivity and strong practicability. The calcitriol compound of the present invention is an important reference substance for the quality control of calcitriol, and can effectively identify the impurities generated in the calcitriol stability test or the storage process, so as to control the drug quality of calcitriol. |
