2,6-Dichlorophenolindophenol sodium hydrate

2,6-Dichlorophenolindophenol sodium hydrate (DCPIP) is a blue redox dye widely used as a visual indicator for ascorbic acid (vitamin C) quantification. Its applications extend to in vitro assays, including monitoring mitochondrial electron transport chain activity, evaluating nanoparticle enzyme mimics, and serving as an electron acceptor in biochemical staining techniques.
