Hazard Information

Chemical Properties
Bromophenol Blue is pink or red powder
Uses
As indicator, pH 3.0 yellow; pH 4.6 purple.
Uses
Bromophenol Blue is an electrophoresis tracking dye also used as an acid-base indicator
Definition
Bromophenol Blue is used as a laboratory indicator, changing from yellow below pH 3 to purple at pH 4.6, and as size marker for monitoring the progress of agarose gel and polyacrylamide gel electrophoresis. It has also been used as an industrial dye.
Purification Methods
Crystallise the dye from *C6H6 or Me2CO/AcOH, and dry it in air. It is an indicator: at pH 3.0 it is yellow and it is purple at pH 4.6. [Beilstein 19/3 V 458.]
