Thymolphthalein Complexone, also known as DTPA-T, is a compound used in analytical chemistry, particularly in complexometric titrations. It is a chelating agent, which means it can form stable complexes with metal ions. Thymolphthalein Complexone is often used to titrate metal ions, particularly calcium, magnesium, and other transitional metal ions.

In the presence of metal ions, Thymolphthalein Complexone undergoes a color change, making it useful for determining the endpoint of the titration. This compound is valuable in various analytical and research applications, especially in the determination of metal ion concentrations in solution.
