Product Description

Bromocresol purple (BCP) or 5′,5″-dibromo-o-cresolsulfophthalein, is a dye of the triphenylmethane family (triarylmethane dyes) and a pH indicator. It is colored yellow below pH 5.2, and violet above pH 6.8. In its cyclic sulfonate ester form, it has a pK_a value of 6.3, and is usually prepared as a 0.04% aqueous solution.Bromocresol purple is used in medical laboratories to measure albumin. Use of BCP in this application may provide some advantage over older methods using bromocresol green. In microbiology, it is used for staining dead cells based on their acidity, and for the isolation and assaying of lactic acid bacteria.

Usage

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.
