Objective:To establish a chiral stationary phase-HPLC method for the enantiomer separation and determination of S-Mon-telukast Sodium impurity in Montelukast Sodium.Methods:The chiral separation was performed on a chiral column CHIRALPAK AGP (4 mm ×150 mm,5 μm) with the mobile phase of ammonium acetate buffer-acetonitrile-methanol gradient elution.The column tem-perature was set at 25℃and the detective wavelength was 344 nm.Results:The enantiomers of Montelukast Sodium were successfully separated and S-Montelukast Sodium optical isomer impurity in Montelukast Sodium were determined.Conclusion:The study provides a simple and reproducible method for the quality control of Montelukast Sodium.
