Description
Bromophenol Blue, R1-EAgent, 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 r1-EAction is reversible. As an ACS grade quality r1-EAgent, 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 R1-EAgent ACS grade products meet the toughest regulatory standards for quality and purity.
