Spectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

متن کاملSpectrophotometric Determination of Chromium . Based on Ion-Pair Formation
A sensitive spectrophotometric method for the determination of trace amounts of chromium(VI) is described. Chromium(VI) forms chlorochromate anion in the presence of acid and chloride ion. The formed anion is extracted in toluene as ion-pair with a cationic dye rhodamine 6G. At 535 nlll absorption maximum molar absorptivity is 2x104 I mol-I em-I. The colour is stable for 4 h and the system obey...
متن کاملExtractive Spectrophotometric Determination of Nisoldipine by Ion-pair Complex Formation
Nisoldipine, a 1-4-dihydropyridine drug is determined by the development of simple and sensitive Extractive Spectrophotometric method. In the present study an ion-pair complex of amino derivative of the Nisoldipine with Bromocresol Green Solution in acidic medium is formed with subsequent extraction of the ion-pair complex in Chloroform. Maximum absorption was seen at the wavelength of 418 nm t...
متن کاملApplication of Ion Pair Extractive Spectrophotometric Methods for the Determination of Gabapentin in Pharmaceutical Formulation
Two new simple, selective, sensitive and economical methods (A and B) have been developed for the analysis of gabapentin in pure and dosage form. The methods were based on ion-pair complexation between drug and dyes like metanil yellow and thymol blue at an optimum pH of 2.8. The colored chromogens were measured at 410 nm (λmax) for method A and 550 nm (λmax) for method B. Calibration curve was...
