The dye phenol red (phenolsulphonphthalein) was chemically brominated to bromophenol blue (3',3',5',5'-tetrabromophenolsulphonphthalein) directly by hydrogen peroxide (20 mM or higher) under acidic pH (0.5-4.5) and moderate temperature (30°C). Since this bromination reaction takes place in the absence of any chemical or biological catalyst, the results represent an important warning concerning a commonly used assay for detecting or screening haloperoxidases. Bromophenol red (5',5'-dibromophenolsulphonphthalein) and another unidentified compound were observed as temporary intermediates. Incubation of the reaction mixture with KCl instead of NaBr did not yield any chlorinated products under the same conditions.
