ISO Certified PH Indicator Bromocresol Green

Bromocresol green (BCG) is a dye of the triphenylmethane family (triarylmethane dyes). It belongs to a class of dyes called sulfonephthaleins. It is used as a pH indicator in applications such as growth mediums for microorganisms and titrations. In clinical practise, it is commonly used as a diagnostic technique. The most common use of Bromocresol green is to measure serum albumin concentration within mammalian blood samples in possible cases of renal failure and liver disease.

Application  Area

1. Used as an acid-base indicator with a pH change range of 3.8 (yellow) to 5.4 (blue-green). The sodium salt aqueous solution is used for spectrophotometric determination of the enthalpy of the developer.

2. As a reagent for the determination of aliphatic hydroxy acids and alkaloids by thin layer chromatography and an extractive separating agent for the determination of quaternary ammonium cations by photometry.
