| Abstract: | Objective:To establish an accurate method for determination of the content of oxacillin sodium for injection. Methods: Oxacillin sodium for injection was determinted with as water by polarimetry. Results:The standard curve was linear in the range of 1 ~ 10 mg/mL. The regression equation was: C = 0. 391 314 5. 261 50a,r = 0. 999 7. The average recovery rate was 102. 1% ,RSD was 1. 83% . Conclusion:The method is simple, rapid, accurate and suitable for the quality control of oxacillin sodium for injection. |
