Resorufin (sodium salt)

Resorufin is a fluorescent probe and the reduced form of the redox indicator dye resazurin (Cay-14322). 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.Formal Name: 7-hydroxy-3H-phenoxazin-3-one, monosodium salt. CAS Number: 34994-50-8. Molecular Formula: C12H6NO3 . Na.
