Difluorinated H2S Fluorescent Probe 1

Description: Difluorinated H2S probe 1 is a fluorescent probe for hydrogen sulfide (H2S).1It selectively fluoresces in the presence of H2S over Zn2+, Fe3+, S2O32-, ClO-, SO32-, H2O2, NO2-, cysteine (Cys), homocysteine (Hcy), and glutathione (GSH) when used at a concentration of 1 µM. Difluorinated H2S probe 1 displays excitation/emission maxima of 365/450 nm, respectively. Target: Others. Smiles: Cc1cc(=O)oc2c(F)c(N=[N+]=[N-])c(F)cc12.
