The main uses of phenolphthalein: 1. medical raw materials in the medical industry: suitable for habitual and stubborn constipation, available in tablets, suppositories and other dosage forms. 2. Used in organic synthesis: mainly used for synthetic plastics, especially for the synthesis of naphthazone polyaryl ether ketone polyaryl ether ketone polymers. This type of polymer has excellent heat resistance, water resistance, and Chemicalbook resistance. Due to its chemical 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. 3. Used as acid-base indicator, indicator for titration of non-aqueous solutions, and reagent for chromatographic analysis.
