The Thermo Scientific™ 2,6-Dichlorophenolindophenol Sodium Salt Hydrate (DPIP) is a high-quality redox indicator widely used in analytical chemistry, biochemistry, and food analysis. With a purity of ≥90% (on dry substance), this compound serves as a reliable reagent for oxidation-reduction reactions and titrimetric assays.
Commonly known as Tillmans’ reagent, DPIP is extensively used for the determination of vitamin C (ascorbic acid) and as an electron acceptor in biochemical assays, particularly in studies involving cellular respiration and enzyme activity. Its distinct color change from blue (oxidized form) to colorless (reduced form) enables easy visual or spectrophotometric detection.
