2,6-Dichlorophenol Indophenol (DCPIP) is a synthetic redox indicator known for its intense blue color in oxidized form and colorless appearance when reduced. It is commonly used in ascorbic acid (vitamin C) quantification, photosynthesis studies, and electron transport chain experiments. In educational and industrial labs, DCPIP serves as a reliable reagent for tracking redox reactions and metabolic activity.
