Used as a pH indicator in analytical chemistry. Used as a tracking dye in gel electrophoresis. Applied in biochemical and molecular biology laboratories. Used in laboratory staining and research procedures.

Its primary purpose is to provide sharp color transitions for acid-base titrations and visualize biomolecule migration in gels due to its low molecular weight and solubility in aqueousorganic media.

Bromophenol Blue is a blue-colored dye commonly used as a pH indicator and tracking dye in laboratories. It changes color depending on the acidity of the solution.
