| | Tetrabromophenol Blue Usage And Synthesis |
| Chemical Properties | beige powder | | Uses | 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 addition, it has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assay, with increasing concentration of urinary protein, TBPB sequentially changes color from pale green to blue. Binding of TBPB to proteins is dependent on pH. |
