2,6-Dichlorophenol Indophenol, (DCPIP, also DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless.DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family.When exposed to light in a photosynthetic system, the dye is decolorised by chemical reduction.CPIP can also be used as an indicator for vitamin C. If vitamin C, which is a good reducing agent, is present, the blue dye, which turns pink in acid conditions, is reduced to a colorless compound by ascorbic acid.
