Biological Information

  • Product Name
    Solvent Red 23
  • Note
    Research use only, not for human use.
  • Brief Description
    Solvent Red 23 is a solvent dye used to color nonpolar substances.
  • Description
    Solvent Red 23 is a solvent dye used to color nonpolar substances.
  • 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.
