Nitro radical anion formation from nimodipine

Reactions of the nitro radical anion of metronidazole in aqueous and mixed solvent: a cyclic voltammetric study

“…Recently electrochemical techniques like cyclic voltammetry [43][44][45][46][47][48][49][50][51][52][53][54][55][56] have been used to study the behaviour of the nitro radical anions.…”

A Selective Voltammetric Method to Follow the Hydrolytic Degradation of Nitrendipine and Nisoldipine

“…From the electrochemical point of view the 1,4-dihydropyridine drugs have been extensively studied, including its voltammetric behavior [10][11][12][13] and the development of electroanalytical methods to be applied to pharmaceutical forms determination [14][15][16]. In addition, photostability studies by electrochemical methods have been also carried out [16][17][18][19][20].…”

Voltammetric studies on nitro radical anion formation from furazolidone and kinetic of the coupled chemical reaction

“…The cyclic voltammogram of furazolidone in protic media shows two reductive peaks due to the 4-electron and 2-electron reduction of the nitro group to form the corresponding hydroxylamine (RNHOH) and amine (RNH 2 ), respectively, as is usual for nitroaromatic compounds [19][20][21][22]25] (data not shown). The reduction mechanism is different on changing from a protic to an aprotic medium.…”

“…Several studies have been reported on the polarographic determination of furazolidone [19,20] in the literature, but little attention has been paid to the formation and kinetics of the coupled chemical reaction of nitro radical anion generated electrochemically from furazolidone. There are some reports on the kinetic parameters of some drugs [21][22][23][24].…”
