Bromocresol green CAS# 76-60-8

Bromocresol green is a light yellow-brown powder. It is slightly soluble in water, soluble in ethanol, ether, ethyl acetate and benzene, and easily soluble in dilute alkali solution. Color change range: pH value is 3.8 (yellow) ~ 5.4 (blue-green).
Applications
1. Acid-base indicator
Indicator widely used in acid-base titration in chemical analysis. When the pH value of the solution is below 3.8, bromocresol green is yellow; when the pH value is above 5.4, it is blue-green; when the pH value is between 3.8 and 5.4, the color gradually changes from yellow to blue-green.
2. Biological stain It can be used for staining in bacteriology, histology, etc.
