MSDS Information
Cresol Red Usage And Synthesis
Chemical PropertiesDark green or brown-red powder
DefinitionChEBI: A member of the class of 2,1-benzoxathioles that is 2,1-benzoxathiole 1,1-dioxide in which both of the hydrogens at position 3 have been substituted by 4-hydroxy-5-methylphenyl groups.
UsesAcid-base indicator.
Purification MethodsCrystallise it from glacial acetic acid. Dry it in air. Dissolve it in aqueous 5% NaHCO3 solution and precipitate it from a hot solution by dropwise addition of aqueous HCl. Repeat the procedure till the UVmax does not increase. [Beilstein 19 IV 1133.]
