Description

90% (HPLC), ACS reagent, Dye content 90 %

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 color from yellow to blue-green at pH 3. 8 to 5. 4. The monosodium salt of bromocresol green is highly ionizable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.
