[Specification]

[Usage]

*Pharmaceutical raw materials: suitable for habitual and stubborn constipation, with various dosage forms such as tablets and suppositories.

*Used for organic synthesis: mainly used for synthesizing plastics, especially for synthesizing diazonaphthalone polyaryletherketone polyaryletherketone polymers. Due to their excellent heat resistance, water resistance, chemical corrosion resistance, heat aging resistance, and good processability, the fibers, coatings, and composite materials made from them are quickly widely used in fields such as electronics, mechanical equipment, transportation, aerospace, and atomic energy engineering.

*Used as an acid-base indicator, an indicator for non aqueous solution titration, and a reagent for chromatographic analysis.

[Storage]
