HPLC Determination of Related Substances of Elagolix Sodium Intermediate 6 and Validation of Analytical Method
Objective:The HPLC method was established for the detection of related substances of elagolix sodium intermediate 6 and validation of analytical method.Method:The WATREX reprosil C18(4 mm×250 mm×5 μm)was used and mobile phase A was 0.1%phosphoric acid in water,the mobile phase B was methanol with gradient elution method at a flow rate of 1.1 mL/min,the UV detector was used with 215 nm,sample injection volume was 15 μL,column temperature was 25℃.Result:Elagolix intermediate 6 is well separated from other intermediates.The results of linearity,solution stability,repeatability and intermediate precision are all meet the requirements.The control limits of each intermediate can all reach its LOQ.Conclusion:The HPLC method has strong specificity,high sensitivity,good precision,simple and high accuracy,and can be used for the determination of related substances of elagolix sodium intermediate 6.
