WitrynaThis document provides guidance on the content and qualification of impurities in new drug substances for registration applications. It applies to drug substances produced by chemical syntheses and not previously registered in a region or Member State. It covers chemistry and safety aspects of impurities in new drug substances. WitrynaImpurity atom MgO can dilute ions of similar size, as for instance Ni or Co forming NiO-MgO and CoO-MgO solid solutions with an infinite range of composition. The effect of progressively replacing Mg by Ni or similar cations (Co, Cu ) on the surface properties has been investigated both experimentally [111, 163,164] and theoretically [165,166]. …

WitrynaThe impurity content of the parent batch was 0.25%-2.5% of total drug substance. The enriched impurity mixtures contained from 3% to 10% of the various impurities. The … Witrynathe relative position of the impurity levels in the TiO 2 band gap. The effect of the impurities on the rutile optical absorption is observed only in the region3,0-4,5 eV, whereas the modified anatase absorption changes significantly in the region3,0-5,5 eV. The band gap remains practically unchanged for modified rutile, whereas it decreases phonepay in laptop
