Efficient oxidizing agents for determination of 2,10-disubstituted phenothiazines.
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, Na...
متن کاملApplication of Capillary Isotachophoresis in Phenothiazines Determination
The phenothiazine derivatives such as: promethazine, chlorpromazine and thioridazine hydrochlorides are used as psychotropic, neuroleptic, local anesthetics, anti-allergic and antiyomiting drugs [1]. The therapeutic interest in these compounds group justifies research to establish different analytical methods for the determination of these drugs in pharmaceutical preparations and biological sam...
متن کاملAnalytical Applications of Reactions of Iron(III) and Hexacyanoferrate(III) with 2,10-Disubstituted Phenothiazines
The presented review is devoted to analytical applications of reactions of Fe(III) and K(3)[Fe(CN)(6)] with 2,10-disubstituted phenothiazines (PT). It was found that iron(III) and hexacyanoferrate(III) ions in acidic media easily oxidized PT with the formation of colored oxidation products. This property has been exploited for spectrophotometric determination of iron(III) ions and phenothiazine...

Natural kaolin as an efficient recyclable catalyst for the synthesis of new 2,4-disubstituted quinolines
Substituted 2, 4- diphenyl quinolines were synthesized by a multicomponent domino reaction of anilines, aldehydes and terminal aryl alkynes. The synthetic pathway involves the formation of an imine, followed by the intermolecular addition of an alkyne to the imine. This intermediate immediately undergoes ring closure and oxidative aromatization. The reaction is catalyzed by natural kaolin, a st...
