Overview

Bromothymol Blue Sodium Salt is a water-soluble sulfonephthalein pH indicator dye widely used in microbiological culture media, analytical chemistry, and laboratory research. It exhibits a clear yellow-to-blue color change over a defined pH range, making it suitable for monitoring acid–base reactions and metabolic activity in culture systems.

In microbiology, Bromothymol Blue Sodium Salt is commonly incorporated into differential media to indicate pH changes resulting from carbohydrate fermentation or other biochemical reactions.
