Product Usage
Main uses of phenolphthalein: 1. Pharmaceutical raw materials in the pharmaceutical industry: suitable for habitual stubborn constipation. There are many dosage forms such as tablets and suppositories. 2. For organic synthesis: it is mainly used for the synthesis of plastics, especially for the synthesis of polyarylene ether ketone and polyarylene ether ketone polymers. Due to the excellent heat resistance, water resistance, chemical corrosion resistance, heat aging resistance and good processing and molding properties, the fibers, coatings and composite materials made of these polymers are quickly widely used in electronics, mechanical equipment, transportation, aerospace Atomic Energy Engineering, military and other fields. 3. Used for acid-base indicator, indicator for non-aqueous solution titration and reagent for chromatographic analysis.
