Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.Reference of 16423-68-0

Effects of cationic and anionic micelles on the redox reaction of Erythrosine B by H2O2 in presence of Cu-Fe nanoparticles was written by Khan, Zaheer;AL-Thabaiti, Shaeel Ahmad;Singh, Bhawana;Rafiquee, M. Z. A.. And the article was included in International Journal of Chemical Kinetics.Reference of 16423-68-0 This article mentions the following:

Kinetic investigation of the degradation of Erythrosine B (EB) by H2O2 and copper-iron bimetallic nanoparticles was carried out spectrophotometrically. The degradation was carried out under the condition of sonication at 40°C. The co-precipitation method was used for the fabrication of CuO/Fe2O3 (Cu-Fe) in an alk. solution and characterized by SEM, XRD, FTIR, TEM, EDS, and BET methods. In the absence of the Cu-Fe, no degradation of EB by H2O2 was observed The presence of Cu-Fe resulted into the degradation of EB by H2O2. The kinetics of the degradation was studied under the conditions of variation of the amount of nanoparticles and at different concentrations of EB, H2O2, H+, surfactants (sodium dodecyl sulfate; SDS and cetyltrimethylammonium bromide; CTABr). The rate of reaction depends on the amount of Cu-Fe and [H2O2]. The rate constant values gave the peaked like curve (with maximum value at pH 3) at different pH. The dye degradation decreased with the increase in presence of (SDS) and (CTABr). In the experiment, the researchers used many compounds, for example, Sodium 2′,4′,5′,7′-tetraiodo-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-bis(olate) (cas: 16423-68-0Reference of 16423-68-0).
