Solvent Red 23 Usage And Synthesis
  • Chemical Propertiesreddish brown powder
  • UsesWeakly acidic azo dye. Biological stain.
  • UsesDye. Biological stain.
  • DefinitionChEBI: A bis(azo) compound that is 2-naphthol substituted at position 1 by a 4-{[(2-methylphenyl)diazenyl]phenyl}diazenyl group. A fat-soluble dye predominantly used for demonstrating triglycerides in frozen sections, but which may also stain some protein bound l pids in paraffin sections.
  • Contact allergensSolvent Red 23 is an oil-soluble red azo-dye used in cosmetic products in Japan. Cases were reported in hairdressers, who also reacted to PPD (the molecule is likely to be hydrolyzed into PPD) and to p-aminoazobenzene. One case of contact dermatitis was reported in the metal industry.
  • Safety ProfilePoison by intraperitoneal route. Moderately toxic by subcutaneous and intrapleural routes. Questionable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
  • Purification MethodsCrystallise the dye from EtOH, EtOH/water or *benzene/absolute EtOH (1:1). [Beilstein 16 II 75, 16 III 148, 16 IV 248.]
