Bromocresol Green sodium salt is used as a pH indicator. It is a pH sensitive triphenylmethane dye useful in various colorimetric detection studies and as an activity tracking dye for DNA agarose gel electrophoresis. It is also used in TLC (thin-layer chromatography) for visualizing compounds containing functional groups having pKa less than 5.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
