At pH 3.8-5.4, it changes color from yellow to blue-green, and is therefore, commonly used as a pH indicator.[1] Application Bromocresol green serves as a pH indicator in biology and medicinal experiments. - It is used widely as a vital stain to study blood-brain permeability. - It has been used in the pH-sensitive colorimetric determination of glutamate decarboxylase activity.[2] - It has also been employed in the evaluation of paper-analytical devices for colorimetric analysis of serum samples.[3] - It is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations, and in charge-transfer complexation processes. - It is used in TLC for the visualization of compounds with functional groups whose pKa is below 5.0. |
