About Phenolphthalein Supplier 77-09-8 Phenolphthalein Powder
Phenolphthalein appears as white or yellowish-white to pale orange fine crystalline powder. Odorless. Aqueous solution is acidic. Colorless to pH 8.5; pink to deep-red above pH 9. Colorless in presence of large amounts of alkali. Tasteless.Phenolphthalein is an organic compound used as a laboratory reagent and pH indicator. Phenolphthalein exerts laxative effects by stimulating the intestinal mucosa and constricting smooth muscles. However, phenolphthalein is no longer used as a laxative due to the suspected carcinogenicity of this compound.
Excellent Indicator for Laboratory AnalysisPhenolphthalein is widely employed as an acid-base indicator in titration procedures due to its distinct color change between pH levels 8.2 to 10.0, enabling precise detection. Its reliability and clarity make it an invaluable chemical reagent for research, quality control, and academic applications.
