  • Thymolphthalein monophosphate disodium hydrate is a chromogenic substrate for the determination of acid phosphatase and alkaline phosphatase. Thymolphthalein is released during the reaction, increases the pH of the medium for easy detection, produces color and stops hydrolysis. Thymolphthalein monophosphate disodium hydrate can be used for the specific detection of prostatic phosphatase in serum[1][2].
