Description
Cresol Red is a sulfonphthalein pH indicator dye. It is used for the determination of pH and finds application in various laboratory and industrial processes. Cresol Red changes color in response to pH variations, transitioning from yellow (pH 7.2) to red (pH 8.8). This makes it valuable for visually assessing whether a solution is acidic or basic. Additionally, Cresol Red is utilized in the analysis of biological samples, as well as in chemical and biochemical research.
