    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.

    Nonaqueous titration is the titration of substances dissolved in nonaqueous solvents. 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. Aqueous / Non-aqueous Titration. Examples of back titrations Assay for Aspirin Tablets BP • Weigh and powder 20 tablets. To a quantity of the powder containing 0.5 g of Aspirin add 30 ml of 0.5M sodium hydroxide VS, boil gently for 10 minutes and titrate the excess of alkali with 0.5M 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

    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.

    Nonaqueous Titration Nonaqueous titration is the titration of substances dissolved in nonaqueous the mostcommon titrimetric procedureused in pharmacopoeial assay. The moisture content in nonaqueous titrations should not be more than 0.05%. Advantages of non-aqueous titration 1. Titration of water insoluble drugs. 2. The method consisted of the titration of the aqueous solution of the tablet containing LNP with 0.1M NaOH potentiometrically and requires fairly large quauntities of LNP for each titration. The present manuscript describes four sensitive titrimetric methods for the determination of LNP in both pure form and in tablet form. A potentiometric titration method in non-aqueous media is proposed for the determination of some commonly used anti-inflammatory agents. The direct potentiometric titration of three anti-inflammatory agents, namely mefenamic acid, fenbufen and ibuprofen; and the indirect potentiometric titration of diclofenac sodium was carried out in acetonitrile solvent using tetra-n-butylammonium hydroxide.
