Abstract：
:A gradient high-performance liquid chromatographic (HPLC) method was developed for the analysis of Synercid freeze-dried powder in routine quality control, stability and compatibility studies. This method is suited for a simultaneous assay of drug substances and impurities. The method was validated for precision, reproducibility, linearity, accuracy and limits of detection. The robustness study that was performed according to an experimental design is described.
