title: Efficient oxidizing agents for determination of 2,10-disubstituted phenothiazines.
abstract: 2,10-Disubstituted phenothiazines are the best drugs in psychiatry. Several methods for their analysis have been reported in the literature. The official methods are based on non-aqueous titration or spectrophotometry. Various oxidizing agents have been used for the spectrophotometric determination of 2,10-disubstituted phenothiazines, e.g. Ce(SO4)2, NH4VO3, K2S208, KIO4, KIO3, KBrO3, FeCl3, NaNO2, H2O2, chloramine T, p-benzoquinone, N-bromosuccinimide. Oxidation reactions of phenothiazines were also used for their determination by flow-injection methods.
