Medchemexpress LLC Sudan III (Sudan Red III) | 85-86-9 | 98.2% | 500 MG
Sudan III is a hydrophobic bisazo dye. Its color changes from orange to blue when exposed to a small volume of sulfuric acid. The acetonitrile solution of Sudan III is most suitable for observing this color-change phenomenon. Studies using H-NMR and UV-Vis spectroscopy indicate that the color change mechanism is due to the protonation of the dye by sulfuric acid. This product is for research use only.
