Tetrabromophenol Blue (CAS# 4430-25-5) is an acid-sensitive, organic dye. Tetrabromophenol Blue has been used in the preparation of radiation-sensitive indicators based on poly(vinyl alcohol). Dyes and metabolites. | [Definition]
ChEBI: Tetrabromophenol blue is a member of benzofurans. | [Biological Activity]
Tetrabromophenol Blue (TBPB) belongs to the group of sulfonephthalein acid-base indicators. It is employed in the potentiometric titration of the halogens with Hg2(NO3)2. In additionit has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assaywith increasing concentration of urinary proteinTBPB sequentially changes color from pale green to blue. Binding of TBPB to proteins is dependent on pH. |
