 | | Standard solution Prepare a solution ofUSP Moricizine Hydrochloride RSinDiluenthaving a known concentration of about 0.10mg per mL.Transfer 10.0mLof this solution to a 500-mLvolumetric flask,add 25.0mLofInternal standard solution,dilute withDiluentto volume,and mix to obtain a solution containing about 0.0020mg ofUSP Moricizine Hydrochloride RSper mL. |
 | | Test solution Transfer about 1g of Moricizine Hydrochloride,accurately weighed,to a 50-mLglass-stoppered centrifuge tube,add 19.0mLof water,and sonicate to dissolve.Transfer 1.0mLof 3Nammonium hydroxide to the tube,insert the stopper,and shake the tube by mechanical means for 30minutes.Centrifuge,draw off a portion of the clear supernatant and filter through a filter having a porosity of 0.5µm or finer. |
