Bromocresol Purple is used as a pH indicator (5.2-6.8 : yellow to blue-purple). Used in spectrophotometric determination of serum-albumin.


Bromocresol purple binds quantitatively with human serum albumin forming a stable complex with absorbance maximum at 600 nm. The intensity of the color produced is directly proportional to the albumin concentration in the sample.


Soluble in water (20 mg/ml), ethanol (80 mg/ml) or methyl cellosolve (300 mg/ml). Soluble in methanol (4 mg/ml).
