Embodiment 1

[0066] Example 1 Simultaneous separation and analysis of Paricalcitol and isomer impurities in Paricalcitol Injection

[0067] 1. Reference substance solution: keep away from light. Get this product Paricalcitol solution, as need testing solution; Accurately measure and take the Paricalcitol reference substance stock solution in right amount, make about containing Paricalcitol 50ng in every 1ml with 50% ethanol quantitative dilution solution, as a contrast solution;

[0068] 2. Sensitivity solution: Accurately measure an appropriate amount of the reference substance solution, and quantitatively dilute it with 50% ethanol to make a solution containing about 5 ng of paricalcitol per 1 ml, as the sensitivity solution;

[0069] 3. System suitability solution: Accurately measure the appropriate amount of paricalcitol reference substance stock solution and impurity 20S, 7Z, 24R, 14R, 22Z reference substance stock solution respectively, and dilute with 50% ethanol to make each 1ml c...

Abstract

The invention belongs to the field of analysis chemistry, and particularly relates to a high performance liquid chromatography method for simultaneously separating and analyzing paricalcitol and isomer impurities in paricalcitol injection. The method is characterized in that a used chromatographic column uses octadecyl bonded silica gel as filling agents and uses methanol-water as a flowing phaseA and methanol as a flowing phase B for elution; the volume ratio of the flowing phase methanol-water is (20 to 30):(70 to 80); the method is used for simultaneously separating and analyzing the paricalcitol and isomer impurities in paricalcitol injection. The method can be used for better separating and analyzing the paricalcitol and isomer impurities 20S and / or impurities 24R and / or impurities 7Z and / or impurities 14R and / or impurities 22Z in the paricalcitol injection; the interference is avoided; the blank that the detection method is not provided by the existing quality standard or literature is made up; the method has the advantages of simplicity, high speed, high accuracy and the like; the technical support can be provided for the quality control of the paricalcitol injection.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to high performance liquid chromatography, a mobile phase and a high performance liquid chromatography for simultaneously separating and analyzing paricalcitol and isomer impurities in paricalcitol injection. Background technique [0002] Paricalcitol is a chemical substance with the molecular formula C27H44O3. Paricalcitol is a synthetic vitamin D analog with biological activity, which modifies the side chain (D2) and A ring (19-nor) of calcitriol, and is mainly used for the treatment of chronic kidney disease. [0003] Paricalcitol is a selective, third-generation vitamin D receptor activator developed by Abbott, which can selectively activate vitamin D receptor (VDR) and selectively up-regulate calcium-sensing calcium in the thyroid gland. sex receptor (CaSR), more efficiently inhibit the synthesis and secretion of PTH in patients with uremia, and less adverse rea...
