Overview

Bromocresol Green is a sulfonephthalein pH indicator dye commonly used in microbiological culture media, analytical chemistry, and laboratory research. It exhibits a distinct color change in response to pH variation, making it suitable for monitoring acid–base reactions and metabolic changes in culture systems.

In microbiology, Bromocresol Green is frequently incorporated into differential media to indicate carbohydrate fermentation or pH shifts resulting from microbial growth. It is also widely used in analytical and biochemical laboratories as a visual pH indicator.
