Spectrophotometric Study of Oxidation Kinetics and Mechanism of Losartan Potassium Using N-chlorosuccinimide

S. Malini, Kalyan Raj, N. Nanda & J. P. Shubha · International Research Journal of Pure and Applied Chemistry · 2015

The kinetics of oxidation of Losartan Potassium [LP] by N-Chlorosuccinimide [NCS] in HCl medium is studied spectrophotometrically at 205 nm at 298 K. The reaction rate shows fractional order dependence on [LP], [HCl] and first order dependence on [NCS]. The reaction rate also sho...

Kinetic Spectrophotmetric Method for Quantitation of Rizatriptan Benzoate in Pharmaceutical Formulations

S. Malini, Kalyan Raj, M. A. Veena & N. Nanda · International Research Journal of Pure and Applied Chemistry · 2015

A simple, sensitive and accurate kinetic spectrophotometric method for the determination of Rizatriptan Benzoate in pure and dosage form is described. The method is based on spectro-photometrically monitoring the oxidation of the drug by a known excess of Chloramine-B in HCl medi...
