What is Phenolphthalein

Product name:Phenolphthalein
CAS
: 77-09-8
Molecular Formula: C20H14O4
Molecular Weight: 318.32
Product description:Belongs to crystal powder, almost insoluble in water. Its characteristic is in acidic and neutral solution is colorless, amaranth in alkaline solution.Phenolphthalein is a kind of weak organic acid, in the pH < 8.2 solution is colorless lactone type structure, when the pH > 8.2 for red quinoid structure.Phenolphthalein is white or yellow microstrip tiny crystals, soluble in water and soluble in alcohol. So often the mixture alcohol solution using phenolphthalein. When the phenolphthalein reagent drip into the water or neutral and acidic aqueous solution, there will be a white haze, this is because alcohol can miscibility with water by arbitrary proportion, poorly soluble in water in the reagent phenolphthalein exhalation.
