Product Description:
Thymolphthalein is widely used as a pH indicator in various laboratory and industrial applications. It is particularly useful in titrations to determine the endpoint of acid-base reactions, as it changes color in the pH range of 9.3 to 10.5, transitioning from colorless to blue. This property makes it valuable in analytical chemistry for accurately measuring the alkalinity of solutions. Additionally, it is employed in educational settings to demonstrate pH changes visually in experiments. In some cases, thymolphthalein is also used in medical diagnostics and research to study physiological processes involving pH variations. Its stability and distinct color change make it a reliable choice for precise pH monitoring.
