Phenol red is typically used as a pH indicator for neutral solutions. The solubility of this product is tested at 100 mg/mL in 1 N Sodium Hydroxide. The material has not been tested for solubility in acids. A 20 mM solution of Acetic acid is expected to have a pH of approximately 3.5. At a pH of 6.8 or less phenol red in solution is yellow. The visual transition interval of this indicator is 6.8 - 8.2, with anything higher than 8.2 being deep red in color.

Description générale
Phenol Red is a phenolsulfonphthalein compound. It is present as a sulfonated hydroxyquinone in weakly acidic aqueous solutions. In alkaline solutions, the dye forms a hydrophilic dianion (a small, red anion and has a larger conjugated system than the yellow hydroxyquinone).
Application
Phenol red is commonly used as a pH indicator in biology and medicine. It is incorporated into microbiological culture media for the identification of Escherichia coli strains. Its clinical diagnostic applications include investigation of gastric and duodenal ulcers and in the assessment of tear function in ophthalmology. Phenol red is also used as a tracer to assess the permeability of the ileal mucosal membrane and to assess bacterial leakage through root-filling materials in dentistry.
Suitable for use as a pH indicator.
