    The importance of narrow slits in the spectrophotometric determination of extinction coefficients has been demonstrated. Care is needed in the B. P. 1958 spectrophotometric tests or assays of apomorphine hydrochloride, chloroquine phosphate, chloroquine sulphate, diiodohydroxyquinoline, naphazoline nitrate, papaverine hydrochloride and. Stock solutions of primaquine diphosphate and chloroquine diphosphate were adjusted to pH 7.0 with O-3 N KOH. Diamino diphenylsulfone DDS was dissolved in water. The molar extinction coefficient of chloroquine at pH 7.0 was assumed to be 18,900 at 342 rnp.’ Preparation of cell sap and ribosomes.

    Employ the developed method for analysis of chloroquine phosphate in pharmaceutical dosage forms, and to compare between the developed method and the official methods for analysis of chloroquine phosphate formulations. The zero order absorption and first derivative spectra were measured for chloroquine phosphate Chloroquine Phosphate is the phosphate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. David C. Warhurst, Jonathan C. P. Steele, Ipemida S.
