Product Description:
m-Cresol purple is widely used as a pH indicator in various scientific and industrial applications. It is particularly valuable in biochemical and microbiological laboratories for monitoring pH changes in culture media and buffer solutions. The indicator transitions from red to yellow in the acidic range (pH 1.2 to 2.8) and from yellow to purple in the slightly alkaline range (pH 7.4 to 9.0), making it useful for precise pH measurements in these ranges. Additionally, m-Cresol purple is employed in titrations to determine the endpoint of acid-base reactions. Its stability and distinct color changes make it a reliable tool for pH-sensitive experiments, such as enzyme activity assays and cell culture studies. In environmental science, it is also used to assess the pH of water samples, aiding in the monitoring of aquatic ecosystems.
