General description
Bromoxylenol blue (BXB) belongs to the sulfonphthalein family. It is also known as 3′,3′′-dibromo-p-xylenol sulfonphthalein.
Application
Bromoxylenol blue is a pH indicator (for pH ranges 6.0-7.6) that is routinely used in acid-base titrations. It is also used for the photometric determination of carboxylic acid impurities in organic liquids and polymers.
Recent applications of bromoxylenol blue include:
- Building pH sensors
- Developing optical sensors for high acidity measurements
- Synthesizing antifungal activity compounds
- Determination of drugs
- In fiber-optic biosensors for the determination and detection of pesticides.
