Vert de bromocresol sel de sodium
Bromocresol Green (BCG), also known as bromcresol green, is a synthetic, anionic, triphenylmethane dye belonging to the phthalein and sulphonphthalein dyes group. It is commonly used as a pH indicator as it changes colour from yellow to blue-green at pH 3,8 to 5,4. The monosodium salt of bromocresol green is highly ionisable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.
- Bromocresol green serves as a pH indicator in biology and medicinal experiments
- It is used widely as a vital stain to study blood-brain permeability
- It is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations, and in charge-transfer complexation processes
- It is used in TLC for the visualisation of compounds with functional groups whose pKa is below 5
- It has been used in the pH-sensitive colorimetric determination of glutamate decarboxylase activity
- It has also been employed in the evaluation of paper-analytical devices for colorimetric analysis of serum samples
- It is suitable as a selective inhibitor in kidney physiology studies
- It is a diagnostic assay manufacturing, hematology, histology
