Description

Intercalating into DNA duplexes, Phenolphthalein (CAS 77-09-8) exhibits pH-dependent spectral shifts enabling detection in forensic blood screening via the Kastle-Meyer test and carbonation assessment in cementitious matrices.

Application

Phenolphthalein (CAS 77-09-8) serves as a critical pH indicator in acid-base titrations, turning from colorless to vivid pink around pH 8.2–10.0. It signals endpoint precision in neutralization reactions. This visual shift enables accurate quantification of unknown concentrations.
