    Summarize

    Phenolphthalein is a weak organic acid, white or slightly yellow fine crystal at room temperature, odorless, tasteless, insoluble in water but easily soluble in alcohol (ethanol), ether. Dissolved in alcohol solutions to make acid-base indicators, colorless in acidic solutions, red in alkaline or alkali metal carbonate solutions, but if in concentrated alkali solutions will form a colorless trimetallic salt, the red faded. In view of this characteristic, it is often used as an indicator for acid-base titration in the laboratory, and the color change range is PH 8.2 ~ 10.0, from colorless to red. When phenolphthalein reagent drops into water or neutral, acidic aqueous solution, there will be a white turbidity, which is because alcohol is easily soluble in water, so that the phenolic phthalein in the reagent is difficult to dissolve in water.

    Chemical property

    White powder. Melting point 258-262℃, relative density 1.27. Soluble in 10 parts alcohol, soluble in dilute alkali solution is dark red, slightly soluble in ether, insoluble in water, odorless, tasteless.

    Pharmacokinetics

    About 15% of the absorbed drugs are absorbed after oral administration, and the absorbed drugs are mainly excreted in urine or feces in the form of glucuronides, and some are also excreted into the intestinal cavity through bile. Chemicalbook is reabsorbed in the intestine, forming entero-liver circulation and prolongating the action time. Soft stool is discharged 4 to 8 hours after administration, and it takes 3 to 4 days to eliminate a single administration. This product is also secreted from breast milk.

    Purpose

    The main uses of phenolphthalein: 1, pharmaceutical industry pharmaceutical raw materials: suitable for habitual stubborn constipation, tablets, suppositories and other dosage forms. 2, for organic synthesis: Mainly used for synthetic plastics, especially the synthesis of diazanadione polyaryl ether ketone polyaryl ether ketone polymer, which has excellent heat resistance, water resistance, chemical corrosion resistance, heat aging resistance and good processing formability. The 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, used for acid-base indicator, indicator for non-aqueous titration, reagent for chromatography.
