EP VIII ASSAY method

Liquid chromatography (2.2.29) as described in the test for related substances with the following modifications. Injection: test solution and reference solutions (a) and (c). System suitability: reference solution (c): – repeatability: maximum relative standard deviation of 1 per cent for the peak due to calcifediol after 6 injections. Calculate the percentage content of C27H44O2 using the chromatogram obtained with reference solution (a) and taking into account the assigned content of calcifediol CRS and, if necessary, the peak due to pre-calcifediol.
