CAS #: 143-74-8 EC Number: 205-609-7 Molar Mass: 354.38 g/mol Chemical Formula: (C₆H₄OH)₂C₇H₄SO₃ Hill Formula: C₁₉H₁₄O₅S Grade: ACS. Phenol red exists as a red crystal that is stable in air. Its solubility is 0.77 grams per liter (g/L) in water and 2.9 g/L in ethanol. It is a weak acid with pKa = 8.00 at 20 °C (68 °F). A solution of phenol red is used as a pH indicator, often in cell culture. Its color exhibits a gradual transition from yellow (λmax = 443 nm ) to red (λmax = 570 nm ) over the pH range 6.8 to 8.2. Above pH 8.2, phenol red turns a bright pink (fuchsia) color.
