Description: Bromophenol Blue, an acid phthalein dye, is utilized both as a tracking dye for electrophoresis and as a pH indicator with a transition range of pH 3 to 4.6. Target: Others. Smiles: O=S1(=O)OC(C=2C1=CC=CC2)(C3=CC(Br)=C(O)C(Br)=C3)C4=CC(Br)=C(O)C(Br)=C4. References: Mendoza L , Gunawardhana T , Batchelor...

Bromophenol blue is commonly used as a pH indicator, a color marker to monitor the progress of agarose or polyacrylamide gel electrophoresis, and a dye to detect proteins and nucleic acids (absorbance at 610 nm), particularly when staining living tissues. As an acid-base indicator its useful pH range is 3-4.6 where...
