General description
Phenol red (phenolsulfonphthalein, PH R) belongs to the class of triphenylmethane dyes. It is a waterͰsoluble anionic dye, mostly used as a pH indicator in cell biology laboratories. Also, in different protocols, it is used to detect H2O2(Hydrogen peroxide).
Application
Phenol red can be used as a:
- Dye in the preparation of phenol red/n-Si photodiode [phenol red/n-type silicon wafer] by spin coating technique. The device is appropriate for photo-detection applications.
- Color-changing dye in the design of fiber optic pH sensor because as the acidity increases, the dye′s absorption properties shift from the green to the blue section of the spectrum.
- Indicator in the determination of freshwater pH.
Features and Benefits
Phenol red is used to detect pH changes in cell culture,
- pH is 6.4 or below yellow color
- pH is 8.2 or above red color.
