Spectrophotometric Determination of Drugs Using 2,3-Dichloro 5,6-dicyano p- benzoquinone as Analytical Reagent
Six drugs viz., Astemizole, Domperidone, Esomeprazole, Losartan potassium, Sumatriptan and Terazosin were tested for the formation of charge transfer complexes with 2, 3-dichloro 5, 6-dicyanopbenzoquinone, (DDQ). Each of these drugs turned the pale yellow colour of reagent i.e DDQ. in CH3CN, to purple and exhibited three bands at 455, 545 and 588 nm due to anion of the reagent whose intensity i...
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 کاملApplication of Mixed Micelle-Mediated Extraction for Selective Separation and Spectrophotometric Determination of P-Aminophenol Impurity in Pharmaceutical Formulations
A procedure for separation/preconcentration of para-aminophenol (PAP) in pharmaceutical formulation, based on cloud point extraction (CPE) as a prior step to determination by UV-Vis spectrophotometry has been developed. The analyte reacted with 4-dimethylamino benzaldehyde (DAB) in acidic media to form a shift base, which were separated and preconcentrated in a mixed micelle of the anionic surf...
متن کاملOrganocatalytic oxidative dehydrogenation of dihydroarenes by dioxygen using 2,3-dichloro-5,6-dicyano-benzoquinone (DDQ) and NaNO2.
The oxidative dehydrogenation of dihydroarenes catalyzed by 2,3-dichloro-5,6-dicyano-benzoquinone(DDQ) and NaNO(2) with dioxygen is reported. The combination of DDQ and NaNO(2) showed high efficiency and high selectivity, compared with other benzoquinones and anthraquinones, e.g., >99% conversion of 9,10-dihydroanthracene with 99% selectivity for anthracene can be obtained at 120 degrees C unde...
متن کاملA novel spectrophotometric determination of caroverine in pharmaceutical formulations via derivatization with Folin-ciocalteu Phenol reagent.
In this study we have reported a new, fast and extraction free spectrophotometric procedure for the assessment of caroverine in pharmaceutical raw and tablet dosage forms. In the reported visible spectrophotometric procedure tungstate in Folin-Ciocalteu phenol reagent is reduced in alkaline medium and produces the blue colored chromogen that shows Λmax at 740nm with the calibration range of 2-2...
