(KLUWER ACADEMIC/PLENUM PUBL, 2002-04)Purpose. To characterize the electrochemical behavior of the photodegradation product of nifedipine, i.e., 2,6-dimethyl-4-(2-nitrosophenyl)-3,5-pyridine-carboxylic acid dimethyl ester (NPD) in different electrolytic media. ...
-
(PERGAMON-ELSEVIER SCIENCE, 2001-08-31)This paper reports a comprehensive study by tast polarography, d.p.p., and cyclic voltammetry on the electrochemical reduction in different electrolytic media of ortho- and meta-nitrotoluene derivatives. Controlled potential ...
-
(1983)The a.c polarographic method has been applied in the study of the glutathione-ampicillin interaction at pH 7.4 and 37°C. Ampicillin shifted the peak potentials of glutathione to less negative values. A linear relation was ...

Electrochemical study of nitrostilbene derivatives: nitro group as a probe of the push-pull effect (ELSEVIER SCIENCE, 2000-09-29)This paper reports electrochemical (tast polarography, differential pulse polarography, cyclic voltammetry) and spectroscopic investigations covering a series of stilbene derivatives having either one or two electron-donating ...
-
(Elsevier , Science Ltd., 1991-11-26)A set of 2,5-dimethoxyamphetarnines differing in their substitution at C4 was studied by differential pulse voltammetry and linear scan cyclic voltammetry in aqueous media. These experiments showed a single oxydation ...
-
(HARWOOD ACAD PUBL GMBH, 2000)This paper deals with the reactivity of the nitro radical anion electrochemically generated from nitrofurantoin with glutathione. Cyclic voltammetry (CV) and controlled potential electrolysis were used to generate the nitro ...
-
(Universidad de Chile, 2015)Los electrodos basados en nanotubos de carbono como material electródico, tienen múltiples ventajas; su bajo costo, buena conductividad eléctrica, un amplio rango de potencial, presentan actividad electro-catalítica muchas ...
