Sastry, C. S. P. published the artcileSpectrophotometric determination of bephenium hydroxynaphthoate, diiodohydroxyquinoline and iodochlorohydroxyquinoline with diazotized dapsone, COA of Formula: C28H29NO4, the publication is Indian Drugs (1989), 26(10), 567-9, database is CAplus.
Bephenium hydroxynaphthoate (I) diiodohydroxyquinoline (II), and iodochlorohydroxyquinoline (III) were determined in pharmaceuticals by a spectrophotometric method based on the drug reaction with the diazonium salt from dapsone and measurement of absorbances at 500 nm for I and 430 nm for II and III. Beer’s law limits, molar extinction coefficients, and Sandell’s sensitivities for these drugs were determined The relative standard deviations for I, II, and III were 1.17, 0.78 and 1.05%, resp.
