Sa. Petrova et al., REDOX PROPERTIES OF PHENAZINE ETHOSULFATE, PHENOSAFRANINE, AND SAFRANINE-T, Russian journal of electrochemistry, 30(11), 1994, pp. 1234-1239
Electrochemical properties of phenazine derivatives such as phenazine
ethosulfate (N-ethyldibenzopyrazonium ethosulfate), phenosafranine (3,
7-diamino-5-phenylphenazonium chloride), and safranine T (3,7-diamino-
2,8-dimethyl-5-phenyiphenazonium chloride) were studied by thin layer
voltammetry on pyrographite electrode. pH-potential diagrams of these
redox systems were plotted. The values of standard potentials and pK o
f ionization for every redox and acid-base equilibria between conjugat
ed species were derived.
