Phenol Red Extra Pure is a highly refined pH indicator dye widely used in biological and chemical laboratories. Appearing as a reddish crystalline powder, it changes color based on pH—yellow in acidic environments (pH < 6.8), red in neutral to slightly basic conditions (around pH 7.4), and fuchsia in more alkaline solutions (pH > 8.2).

This Extra Pure grade is particularly suited for cell culture media, where it helps monitor pH fluctuations during cell growth and metabolic activity. It is also employed in analytical chemistry, water quality testing, and titrations. Phenol Red is stable under normal storage conditions but should be kept in a dry, tightly sealed container away from strong acids or bases. Proper lab safety protocols—such as wearing gloves and goggles—are recommended when handling the powder or concentrated solutions.
