    Product Description

    Product Description

    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.

    Phenolphthalein is one of those chemicals that is commonly used in the chemistry laboratory to tell if a solution is acidic or alkaline . These chemicals are called acid - base indicators and used as indicator for acidimetric titrations. 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.
