Quantitative determination of Drugs & Pharmaceuticals using p- Chloranilic acid as Reagent
Nine drugs viz., Famotidine, Ketorolac tromethamine, Dextromethorphan, Quetiapine, Salmeterol, Sumatriptan, Tamoxifen, Torsemide and Pantoprazole turned the pale yellow colour of reagent viz., p-chloranilic acid, in CH3CN, to purple and exhibited a band at 520nm due to anion of the reagent whose intensity increased with increase in the concentration of the drugs and formed a basis for quantitat...
متن کاملSpectrophotometric Determination of Drugs Using Iodine As Analytical Reagent
Six drugs viz., Astemizole, Cisapride, Domperidone, Pantoprazole, Rabeprazole and Trazadone were tested for the formation of charge transfer complexes with Iodine. Each of these drugs turned the violet coloured i.e iodine , in CH2Cl2, to brown and exhibited a new band at 366nm in addition to the original band of iodine at 510nm due to anion of the reagent whose intensity increased with increase...
متن کاملRapid Spectrophotometric Determination of Trace Amounts of Chromium Using Variamine Blue as a Chromogenic Reagent
Um método espectrofotométrico simples, rápido e sensível foi desenvolvido para a determinação traço de cromo usando azul de Variamina como reagente cromogenico. O método proposto consiste na reação de cromo(VI) com iodeto de potássio, em meio ácido, liberando iodeto que então oxida o azul de Variamina formando um composto de cor violeta com o máximo de absorção em 556 nm. A lei de Beer é obedec...
متن کاملSpectrophotometric determination of osmium(VIII) in trace amounts using ethylene thiourea (ETU) as chromogenic reagent
A simple and highly sensitive spectrophotometric method has been described for the determination of trace amount of osmium(VIII) using ethylene thiourea (ETU) as a chromogenic reagent. The method is based on the formation of an instantaneous purple coloured complex at room temperature by the reaction of osmium(VIII) with ETU in strongly acidic (pH=1) solution having absorption maximum at 490 nm...
متن کاملSpectrophotometric Determination of Eflornithine Hydrochloride using Vanillin as Derivative Chromogenic Reagent
Purpose: To develop and validate a spectrophotometric method for the quantitative determination of eflornithine hydrochloride as a pure compound and in pharmaceutical formulations. Methods: The method involved the reaction of the target compound with vanillin reagent at specific pH 5.6 to produce a green reddish color chromogen. The derivative chromogen exhibits absorption maxima at 578 nm. At ...
