BROMOXYLENOL BLUE INDICATOR GRADE

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.
