In this module, you learn about the Ph. Eur. policy on impurity control. It covers all types of impurities, whether they are organic, inorganic (including elemental impurities), solvents or DNA-reactive impurities such as N-nitrosamines. Witrynaindicates that the impurity has a toxicological hazard. Relevant impurities have the inherent capacity to cause harmful/unacceptable effects within the meaning of Article 4(2) and (3). Compared to the active substance, relevant impurities show additional (or more severe) toxic properties (in the sense of the above given properties). chippings sizes
