Bromocresol green indicator (BCG) is a dye of the triphenylmethane family (triarylmethane dyes).
It belongs to a class of dyes called sulfonephthaleins. It is used as a pH indicator in applications
such as growth mediums for microorganisms and titrations.
Application
BROMOCRESOL GREEN INDICATOR SOLUTION used as a pH indicator and as a tracking dye for DNA agarose gel electrophoresis. It can be used in its free acid form (light brown solid), or as a sodium salt (dark green solid). Intended Use Bromo Cresol Green Indicator is recommended as a pH indicator in growth medium for microorganisms.
Dosage
In aqueous solution, bromocresol green will ionize to give the monoanionic form (yellow), that further deprotonates at higher
pH to give the dianionic form (blue), which is stabilized by resonance The acid dissociation constant (pKa) of this reaction
