Bromocresol Green, commonly known as BCG, is a synthetic triphenylmethane dye used as a pH indicator and analytical reagent.

It changes from yellow under acidic conditions to blue under alkaline conditions, with a transition range around pH 3.8 to 5.4.

The product is widely used in titrations, biological assays, and analytical chemistry.

• pH indicator: provides a clear yellow-to-blue color transition in titrations.

• Analytical chemistry: used in colorimetric assays and buffer preparation.

• Biological assays: applied in protein and enzyme-related analytical systems.

• Laboratory research: supports pH monitoring in aqueous and biological systems.
