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.
