Bromophenol blue is an acid phthalein dye primarily used as a tracking dye for electrophoresis and as a pH indicator with a transition range of pH 3 to 4.6. It also functions as a sensor for detecting substances like ammonia, drugs, proteins, and amino acids, showing a strong absorbance at 610 nm when bound to proteins. This product is intended for research use only.
