Description

General description

2,6-Dichloroindophenol sodium salt hydrate is a blue redox dye.

Application

2,6-Dichloroindophenol sodium salt hydrate is suitable for vitamin C determination. 2,6-Dichloroindophenol (DCIP) may be used in the following studies:
• As redox dye to investigate the efficiency of gold nanoparticles (Au-NP) for enzymatic activity of glucose oxidase (GOx).
• To compose UVB specific dosimeter.
• Quantification of vitamin C (L-ascorbic acid) in fruit juices.
• As substrate in NQO1 assay to investigate the liver cytosolic NQO1 activity spectrophotometrically.
• Mitochondrial succinate CoQ oxidoreductase (complex II) activity assay.
