1. Evaluate the quality of diprofillin in the solution for injection by quantitative content (should be according to the FS 0.0925-0.1060 g / ml).
1.0 ml of the drug was made up to the mark with water in a 100 ml volumetric flask (solution A). 1.0 ml of solution A was made up to the mark with water in a 100 ml volumetric flask. The optical density of the resulting solution at 273 nm in a cuvette with a layer thickness of 1.0 cm is 0.527. The optical density of a solution of CO diprofyllin, prepared according to the same scheme from a sample weighing 0.09985 g, is 0.527 at 273 nm.
