Applications
Bromocresol Green is useful in a variety of colorimetric detection technologies. It is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations and in charge transfer complexation processes. In TLC, it is used for visualisation of the compounds with functional groups whose pKa is below 5.0. Bromocresol green is a pH indicator and reagent. It has been used in serum albumin determinations and 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.
