Spectrophotometric flow injection procedure to indirect determination of paracetamol in pharmaceutical formulations using o-tolidine as reagent
A spectrophotometric flow injection method for the determination of paracetamol in pharmaceutical formulations is proposed. The procedure was based on the oxidation of paracetamol by sodium hypochloride and the determination of the excess of this oxidant using o-tolidine dichloride as chromogenic reagent at 430 nm. The analytical curve was linear in the paracetamol concentration range from 8.50...
متن کاملFlow Injection Turbidimetric Determination of Acetylcysteine in Pharmaceutical Formulations Using Silver Nitrate as Precipitant Reagent
Um procedimento de análise por injeção em fluxo turbidimétrico simples, exato e preciso é descrito para determinação de acetilcisteína em formulações farmacêuticas. O procedimento é baseado na precipitação da acetilcisteína com solução de nitrato de prata em meio ácido e o sal insolúvel produzido foi monitorado em 410 nm. A curva analítica para a acetilcisteína foi linear no intervalo de concen...
متن کاملIndirect flow-injection spectrophotometric determination of meloxicam, tenoxicam and piroxicam in pharmaceutical formulations.
A simple and sensitive indirect spectrophotometric method for the assay of meloxicam (MX), tenoxicam (TX) and piroxicam (PX) in pure and in pharmaceutical formulations by flow injection analysis (FIA) has been proposed. The method is based on the oxidation of these drugs by a known excess of N-bromosuccinimide (NBS) in an acidic medium, followed by a reaction of excess oxidant with chloranilic ...
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 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...
