Product Description:
Chlorophenol red is commonly used as a pH indicator in various laboratory applications. It is particularly useful in microbiological and biochemical experiments to monitor pH changes in culture media or solutions. The indicator changes color from yellow to red as the pH shifts from acidic to slightly alkaline, typically in the range of 4.8 to 6.7. This property makes it valuable for assessing the pH of cell cultures, enzyme reactions, and other biological processes. Additionally, it is employed in titration experiments to determine the endpoint of acid-base reactions. Its stability and distinct color transition ensure reliable and accurate pH monitoring in scientific research.
