Bromocresol Purple Usage And Synthesis
Chemical PropertiesCrystalline
UsesAs indicator, pH 5.2 yellow; pH 6.8 purple.
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-methylphenyl groups. A hydrophilic dye that is used as a pH indicator and to measure serum albumin concentrations.
Purification MethodsDissolve the dye in aqueous 5% NaHCO3 solution and precipitate it from a hot solution by dropwise addition of aqueous HCl. Repeat this until the UV/VIS-extinction did not increase at 419nm. It can also be recrystallised from *benzene. It is an indicator: at pH 5.2 (yellow) and pH 6.8 (purple). [Beilstein 19/3 V 460.]
