to:
Mix a quantity of Oral Suspension, equivalent to about 200 mg of mebendazole, with 20 mL of a mixture of chloroform and 96 percent formic acid (19:1). Warm the suspension on a water bath for a few minutes, cool, and filter through a medium-porosity, sintered-glass filter. Apply 10 μL of this solution and 10 μL of a Standard solution of USP Mebendazole RS in a mixture of chloroform and 96 percent formic acid (19:1) containing 10 mg per mL to a suitable thin-layer chromatographic plate (see Chromatography <621>) coated with a 0.25-mm layer of chromatographic silica gel mixture. Allow the spots to dry, and develop the chromatogram in a solvent system consisting of a mixture of chloroform, methanol, and 96 percent formic acid (90:5:5) until the solvent front has moved about three-fourths of the length of the plate. Remove the plate from the developing chamber, mark the solvent front, allow the solvent to evaporate, and examine the plate under short-wavelength UV light: the R_F value of the principal spot obtained from the Test solution corresponds to that obtained from the Standard solution.
