Product Name	Phenolphthalein
CAS No.	77-09-8
other name	Phenolphthalein powder
Appearance	white powder
Packing	25kg/drum
Specification	chemicals
Shelf life	2 Years

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.

Application

This product is a commonly used acid indicator, and the color change range is pH 8.2 (colorless) -10.0 (red).
