Bromkresolgrün Natriumsalz

Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.
