Spectrophotometric Determination of Tropicamide in Bulk and Pharmaceutical Formulations
A simple and sensitive extractive spectrophotometric method is described for determination of tropicamide. The method is based on the reaction of tropicamide and bromocresol green. The ion-paired colored complex was extracted with chloroform at pH 3. The extracted complex showed maximum absorbance at 423 nm. The complex was stable up to 2 days and obeyed Beer's law over the concentration r...
متن کاملDetermination of Pioglitazone Hydrochloride in Bulk and Pharmaceutical Formulations by Uv Spectrophotometric Method
UV spectrophotometric method was developed and validated for the analysis of pioglitazone in tablets. The analyses were performed in Phosphate buffer (pH 7.4). Beer’s law was valid in concentration range of 10-50 mcg/ml and UV detection was done at 238 nm. The developed method was validated respect to linearity, precision, accuracy, selectivity / sensitivity applied to the determination of Piog...
متن کاملDevelopment of new spectrophotometric methods for the determination of Alfuzosin hydrochloride in bulk and pharmaceutical formulations
Two simple and sensitive methods A and B for the spectrophotometric determination of Alfuzosin hydrochloride have been described. These methods are based on the formation of purple color and redviolet colored chromogens obtained when the drug was diazotized with nitrous acid followed by coupling with Phloroglucinol and Resorcinol, exhibiting λmax at 520 and 600 nm respectively. These methods ob...
متن کاملVisible spectrophotometric determination of Rosuvastatin in bulk and pharmaceutical formulations
Two simple and sensitive methods have been developed for the estimation of rosvastatin in bulk and in pharmaceutical dosage forms. Method A is based on the oxidative coupling of rosvastatin with MBTH in presence of oxidant cerric ammonium sulphate and the λmax of the colored species was found to be 658 nm. Method B is based on the formation of co-ordination complex between rosvastatin and cobal...
