Bromocresol Green With CAS 76-60-8
Bromocresol green is slightly soluble in water and soluble in ethanol, ether, ethyl acetate, and benzene. Very sensitive to alkali, Bromocresol green turns a special blue-green color when encountering alkaline aqueous solutions. Bromocresol green can be used as an indicator, appearing yellow at pH 3.8 and blue-green at pH 5.4.

1.Bromocresol green is Cell staining agent
2.Bromocresol green is Acid-base indicator, pH color change range 3.8 (yellow) to 5.4 (blue-green)
3.Bromocresol green sodium salt is commonly used in colorimetric determination of acidity and alkalinity. Bromocresol green's sodium salt solution is used as a colorimetric agent for measuring pH value by spectrophotometry. Used as a reagent for thin layer chromatography to determine aliphatic hydroxyacids and alkaloids, and as an extraction and separation agent for photometric determination of quaternary ammonium cations.
