Eriksson, A.; Nyholm, L. published the artcile< Coulometric and spectroscopic investigations of the oxidation and reduction of some azosalicylic acids at glassy carbon electrodes>, Safety of Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is coulometry spectroscopy oxidation reduction azosalicylic acid glassy carbon electrode.
Constant potential coulometry in combination with cyclic voltammetry, UV-visible, 1H and 13C NMR spectroscopy were used to identify the oxidation and reduction products for some structurally similar azosalicylic acids, including the azosalicylic drugs Sulfasalazine and Olsalazine. The experiments were carried out in aqueous solutions at pH 4.5 to 10.0. Voltammetric and UV-visible spectroscopic comparisons involving standard substances confirm that all compounds studied, except 4,4′-azobis[2-hydroxybenzoic acid], are reduced in an overall four-electron process to their corresponding amines. For 4,4′-azobis[2-hydroxybenzoic acid], the reduction involves only two electrons and most likely gives rise to the corresponding hydrazo compound The oxidations of 3,3′-azobis[6-hydroxybenzoic acid] (Olsalazine), 3,3′-azoxybis[6-hydroxybenzoic acid] and 2-hydroxy-5-[(3′-carboxy-2′-hydroxyphenyl)azo]benzoic acid involve an initial two-electron step. Based on UV and NMR spectroscopic data, probably the oxidation of 3,3′-azobis-[6-hydroxybenzoic acid] gives rise to a 2,2′-dicarboxy-1,4-dibenzoquinone azine.
Electrochimica Acta published new progress about Coulometry. 6054-98-4 belongs to class alcohols-buliding-blocks, and the molecular formula is C14H8N2Na2O6, Safety of Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate).
