生物活性

Sudan III is a hydrophobic bisazo dye[1].

体外研究
(In Vitro)

Sudan III changes its color from orange to blue against a small volume of sulfuric acid, and the acetonitrile solution of Sudan III is the most suitable for observing the color-change phenomenon. H-NMR and UV-Vis spectroscopic studies show that the color-change mechanism of Sudan III against sulfuric acid is due to the protonation of the dye by sulfuric acid[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
