General description
Tetrabromophenol blue is an acid-sensitive triphenylmethane dye widely employed as an industrial dye for food, drugs, cosmetics, and laboratory indicators. It belongs to the group of sulfonephthalein acid-base indicators. It is commercially available as a sodium salt.
Biochem/physiol Actions
Tetrabromophenol Blue sodium salt has two tautomeric forms that are differently coloured: blue at pH > 4.6 and yellow at pH < 3, and is thus employed as a pH indicator.

Bromophenol blue and tetrabromophenol blue are two triphenylmethane dyes. Triphenylmethane derivatives and their structurally related compounds, such as fluoresceins and xathenes, are widely used as industrial dyes for foods, drugs, cosmetics, textiles, printing inks or laboratory indicators.
