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].

生物活性
Sudan I (Solvent Yellow 14) is a diazo-conjugate red dye and can be used as an additive to products such as oils, solvents or polishes. Sudan I inhibits growth of bacterial strains Clostridium perfringens and L. rhamnosus[1].
体外研究 (In Vitro)
Sudan I is a monoazo dye with the chemical formula of 1-phenylazo-2-naphthol. Sudan I can cause tumors in the liver or urinary bladder in mammals and is a potential mutagen and carcinogen for humans. Sudan I induces genotoxic effect in HepG2 cells and increases mutagenic and clastogenic effects in the MCL-5 cell lines compared to the AHH-1 cell line. In addition, Sudan I also gives positive results in Salmonella Typhimurium mutagenicity tests with S9 activation, a post-mitochondrial fraction prepared from the livers of rats[1].

生物活性
Sudan Black B, a fat-soluble diazo dye, is a histochemical stain. Sudan Black B can be used for staining of neutral triglycerides and lipids[1].
体外研究 (In Vitro)
Sudan Black B works also in frozen material, and therefore can be complementarily used with SA-β-gal when investigating senescence. Sudan Black B is a highly lipophilic agent that exhibits high affi nity to the lipid compartment of lipofuscin. The positive Sudan Black B-lipofuscin reaction reveals blue-black intracellular granules in cells and frozen tissues and brown to black granules in FFPE tissues under the light microscope.
