1. When determining water according to the Fischer method, 1.45 ml of the reagent was used for titration of a sample of benfotiamine weighing 0.05078 g, and 0.4 ml of the control experiment. When setting the titer of Fisher´s reagent for titration of a sample of water weighing 0.04214, 10.8 ml of the specified reagent went, the control experiment - 0.4 ml. Does the analyzed sample of benfotiamine meet the requirements of the FS in terms of "Water" (no more than 9.0%).
