说明

一般描述

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).
 

应用

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.

特点和优势

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.
