Spectrophotometric determination of urea in dermatologic formulations and cosmetics.
A rapid, relatively sensitive, and low-cost method for the determination of water-soluble urea content in dermatological therapy products and cosmetics is proposed using a new spectrophotometric assay with water as the only extraction solvent. Spectrophotometric methods involve addition of a known excess of bromate to urea in an acid medium, followed by the determination of residual bromine and...
متن کاملSpectrophotometric 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 کاملDerivative Spectrophotometric Method for Determination of Losartan in Pharmaceutical Formulations
Losartan, a highly effective blood pressure lowering agent, has been widely used for the treatment of hypertension. A fast and reliable method for the determination of losartan was highly desirable to support formulation screening and quality control. A first derivative UV spectroscopic method was developed for determination of losartan in the tablet dosage form. The first derivative spectrum r...
متن کاملSpectrophotometric Determination of Valacyclovir in Pharmaceutical Formulations
A simple spectrophotometric method has been developed for the estimation of valacyclovir in pharmaceutical preparations. The method is based on the reaction of the valacyclovir with methanolic solution of para dimethyl amino benzaldehyde (PDAB) in acidic condition producing Schiff base having absorption maximum at 400 nm. Beer’s law is obeyed in the concentration of 50-250 μg/mL of valacyclovir...
متن کاملSpectrophotometric determination of methyldopa in pharmaceutical formulations
A new, simple, precise, rapid and low-cost spectrophotometric method for methyldopa determination in pharmaceutical preparations is described. This method is based on the complexation reaction of methyldopa with molybdate. Absorbance of the resulting yellow coloured product is measured at 410 nm. Beer’s Law is obeyed in a concentration range of 50 – 200 μg ml methyldopa with an excellent correl...
