Bromophenol Blue, Water Soluble, Reagent, ACS is used as an acid-base indicator and a gel electrophoresis color marker. As an acid-base indicator its useful range lies between pH 3.0 and 4.6. At pH 3.0 it is blue and at pH 4.6 it changes to yellow. The reaction is reversible. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
