Solvent Red 24 Usage And Synthesis
  • Chemical Propertiesdark red to brown crystals or powder
  • UsesSolvent Red 24 has been used to promote wound healing and biological stain.
  • UsesFat stain.
  • DefinitionChEBI: A bis(azo) compound that is 2-naphthol substituted at position 1 by a {2-methyl-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 protei bound lipids in paraffin sections.
  • Safety ProfileQuestionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
  • Purification MethodsCrystallise the dye from EtOH/water or acetone/water. [Beilstein 16 IV 249.]
