Bromothymol Blue Usage And Synthesis
Chemical PropertiesPale purple crystalline powder
UsesBromothymol blue is a chemical indicator for weak acids and bases.
UsesAs indicator, pH 6.0 yellow; pH 7.6 blue.
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 3-bromo-4-hydroxy-5-isopropyl-2-methylphenyl groups.
Purification MethodsDissolved the dye in aqueous 5% NaHCO3 solution and precipitate it from the hot solution by dropwise addition of aqueous HCl. Repeat this until the extinction at max 420nm does not increase. It is an indicator: aqueous solutions are yellow at pH 6.0, and blue at pH 7.6. [Beilstein 19/3 V 461.]
