Structure of phenol red
WebPhenol red exists as a red crystal that is stable in air. …. A solution of phenol red is used as a pH indicator, often in cell culture. Its color exhibits a gradual transition from yellow ( max = 443 nm) to red ( max = 570 nm) over the pH range 6.8 to 8.2. Above pH 8.2, phenol red turns a bright pink (fuchsia) color. WebPhenol red, also known as phenolsulfonphthalein, is a pH indicator dye that exhibits a gradual transition from yellow to red over a pH range of 6.2 to 8.2 (Figure 2). Above 8.2 the dye turns a bright fuchsia color. Why is phenol red used in culture media? Phenol red is used as a pH indicator.
