Resorufin is a fluorescent probe and the reduced form of the redox indicator dye resazurin. It can be further reduced to hydroresorufin, which is non-fluorescent. Resorufin has been used in the synthesis of resorufin-based fluorescent probes. It has also been used for the direct measurement of solvent-solute hydrogen bond dynamics with distinct absorption and emission peaks in solvents with strong hydrogen bonds and overlapping peaks in solvents with weak hydrogen bonds. It displays excitation/emission maxima of 570/580 nm, respectively.
