Phenolphthalein, a compound with the CAS number 77-09-8,
With a molecular formula of C20H14O4 and a molar mass of 318.32
It is a stable, colorless to faintly yellow crystalline powder that is soluble in ethanol and alkali solutions,
slightly soluble in ether, and insoluble in water.
it has a density of 1.27 g/cm³ at 32 °C, a melting point of 261-263 °C,
and a boiling point of approximately 417.49 °C.
In laboratories, phenolphthalein is a widely used acid-base indicator, changing color from colorless to red over a pH range of 8.2 to 10.0.
Beyond the lab, it's employed in industrial and agricultural production for pH control and titration analysis.
In the pharmaceutical industry, it's used as a laxative due to its ability to stimulate intestinal peristalsis.
However, it can occasionally cause allergic reactions like dermatitis.
Phenolphthalein also plays a crucial role in organic synthesis, particularly in creating high-performance polymers used in electronics, aerospace, and military applications.
Its properties make it suitable for synthesizing phthalazinone polyaryl ether ketone polymers, known for their excellent heat and chemical resistance.
Additionally, it serves as a non-aqueous titration indicator and a reagent in chromatographic analysis.
Despite its many uses, caution is advised due to its irritant nature and potential toxicity. Phenolphthalein must be handled with care, especially in pharmaceutical applications.
