Use

Phenolphthalein is a commonly used acid indicator with the range of color change between pH 8.2 (colorless) to 10.0 (red). It is also a drug, can be used as a laxative, acting on the colon for the treatment of constipation. It can be used as a pharmaceutical raw material in the pharmaceutical industry: it is suitable for habitual intractable constipation, and it has a variety of dosage forms such as tablets and suppositories. Also used in organic synthesis: mainly used in the synthesis of plastics, especially the synthesis of phthalazinone polyaryl ether ketone polyaryl ether ketone polymers, which have excellent heat resistance, water resistance, and chemical resistance Fibers, coatings and composite materials made from them are quickly widely used in electronic appliances, mechanical equipment, transportation, aerospace, atomic energy engineering, military and other fields. Phenolphthalein can be used as an acid-base indicator, an indicator for non-aqueous titration, and a reagent for chromatography.
