Background:

IC50: N/A

Bromophenol blue (3',3",5',5"-tetrabromophenolsulfonphthalein) is widely used in gel loading buffers. Bromophenol blue is experimentally used as acolor marker, apH indicator, and a dye. Bromophenol blue can be prepared by slowly adding excess bromine to a hot solution ofphenolsulfonphthaleinin the presence of glacial acetic acid.

In vitro: Previous results showed that the adsorption process of bromophenol blue increased with the increase in the concentration of α-chitin nanoparticles (CNP), contact time and temperature, while the adsorption process decreased with increase in the initial dye concentration and strong acidic pH. The Fourier transform infrared spectroscopy results confirmed that the interaction between Bromophenol blue and CNP involved physical adsorption. The adsorption process obeyed Langmuir isotherm and pseudo second order kinetics more effectively. The isotherm and kinetic models confirmed that CNP could be used as a suitable adsorbent material for the removal of dyestuff, such as Bromophenol blue, from effluents [1].

In vivo: So far, bromophenol blue has not been employd in animal in vivo study.

Clinical trial: N/A
