    Assay of chloroquine by non aqueous titration


    It is the most common titrimetric procedure used in pharmacopoeial assays and serves a double purpose: it is suitable for the titration of very weak acids and very weak bases, and it provides a solvent in which organic compounds are soluble. The most commonly used procedure is the titration of organic bases with perchloric acid in anhydrous acetic acid.

    With. The method permits a rapid determination of different types of compounds common in the pharmacy of today amines and heterocyclic nitrogen compounds, amino-acids, alkali and organic salts of weak acids and of hydrogen halides. Acetic acid is the solvent most commonly used in the non-aqueous titration of bases. The fundamental work on the method was carried out Non Aqueous Titration Theory. The need for non aqueous titration arises because water can behave as a weak base and a weak acid as well, and can hence compete in proton acceptance or proton donation with other weak acids and bases dissolved in it. Nonaqueous titration is the titration of substances dissolved in solvents other than water. It is the most common titrimetric procedure used in pharmacopoeial assays and serves a double purpose it is suitable for the titration of very weak acids and very weak bases, and it provides a solvent in which organic compounds are soluble.

    The Karl Fischer titration for water content is another nonaqueous titration, usually done in methanol or sometimes in ethanol. These assays sometimes take some perfecting in terms of being able to judge the endpoint precisely.

  3. Non aqueous titration refers to a type of titration in which the analyte substance is dissolved in a solvent which does not contain water. This procedure is a very important one in pharmacopoeial assays. Non Aqueous Titration Theory. The need for non aqueous titration arises because water can behave as a weak base and a weak acid as well, and can hence compete in proton acceptance or proton.

    The feasibility of a titration in a given sol- vent can be calculated from. Abstract A non-aqueous titration method was developed to assay the insensitive. Keywords 1, 1-diamino-2, 2-dinitroethene, FOX-7, non-aqueous titration.different nitro pdf pro 7 0 2 8 x86 The nonaqueous titrimetric method was applied as parallel validation estimation. This involves volumetric determination of the chloroquine in non- aqueous solvent using 0.1M perchloric acid and crystal violet as indicator. Acidimetry in Non-Aqueous Titrations In order to perform feasible titrations of weak bases, the solvent system should be selected specifically in such a fashion so as to eliminate as far as possible the competing reaction of water for the proton besides enhancing the strength of the basic species.

Hydroxychloroquine sulfate is a colorless crystalline solid, soluble in water to at least 20 percent; chemically the drug is 2-4-7-Chloro-4-quinolylaminopentylethylamino ethanol sulfate 11. PLAQUENIL hydroxychloroquine sulfate tablets contain 200 mg hydroxychloroquine sulfate, equivalent to 155 mg base, and are for oral administration.
