In the realm of analytical chemistry, precise indicators are crucial for obtaining accurate results. Thymolphthalein (CAS 125-20-2) is one such compound, widely recognized for its function as an acid-base pH indicator. Its specific color transition characteristics make it invaluable in numerous laboratory procedures and industrial quality control applications. For professionals looking to purchase Thymolphthalein, understanding its core properties and applications is the first step toward ensuring effective procurement.

Thymolphthalein is characterized by its distinct pH-dependent color change. It appears colorless in solutions with a pH below 9.3, and as the pH rises, it transitions to a vivid blue color above pH 10.5. This specific range makes it highly suitable for titrations where the endpoint occurs in a strongly alkaline region. Its molecular formula is C28H30O4, with a molecular weight of approximately 430.54 g/mol. Typically supplied as a white crystalline powder, it is often dissolved in ethanol for use as an indicator solution.

The utility of Thymolphthalein extends across several key areas. Its primary application is as an indicator in acid-base titrations, particularly those involving strong bases, ensuring accuracy in chemical analysis. It is also employed in alkalinity testing, a common practice in environmental monitoring and industrial process control. Furthermore, Thymolphthalein has found applications in areas like forensic science and in the formulation of disappearing inks, showcasing its versatility.
