Phenolphthalein is a weak organic acid, which appears as white or slightly yellow fine crystals at room temperature. It is odorless and tasteless. It is difficult to dissolve in water but easily soluble in alcohol (ethanol) and ether. It is dissolved in alcohol solution to make an acid-base indicator. It is colorless in acidic solution and red in alkali solution or alkali metal carbonate solution. However, if it is in concentrated alkali solution, it will produce colorless trimetallic acid. salt, red color fades

1. Pharmaceutical raw materials for the pharmaceutical industry: suitable for habitual and stubborn constipation, available in tablets, suppositories and other dosage forms.
2. Phenolphthalein used in organic synthesis: mainly used for synthetic plastics, especially for the synthesis of naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. This type of polymer has excellent heat resistance, water resistance, and chemical resistance. Due to its corrosion resistance, heat aging resistance and good processing and formability, fibers, coatings and composite materials made from it are soon widely used in electronic appliances, mechanical equipment, transportation, aerospace, atomic energy engineering and military fields.
3. Phenolphthalein used as acid-base indicator, indicator for titration of non-aqueous solutions, and reagent for chromatographic analysis.
