Step 5. In medicine, phenolphtaleine was used as a laxative, but is now being removed from over-the-counter laxatives because of concerns over carcinogenicity. Add a Physical Property of Phenolphthalein. Contains yellow bodies which impart characteristic color. Shelf Life 60 Months. The compound has been observed to turn orange at pH 0, clear between pH 0-8.2, fuchsia between pH 8.2-12, and clear again at a pH above 12.It has been postulated that the mutagenic effects of Phenolphthalein at high doses can be attributed the enhancement intracellular free oxygen radicals. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). As an indicator, phenolphthalein's pH range is between 8.2-12 where it changes from colorless to pink/fucshia.In very acidic solutions near pH 0 phenolphthalein appears orange. 117, p. 215, Literature: Baeyer Chemische Berichte, 1879 , vol.
