Difluorinated H2S Fluorescent Probe 1

Difluorinated H2S probe 1 is a fluorescent probe for hydrogen sulfide (H2S). It 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.Formal Name: 7-azido-6,8-difluoro-4-methyl-2H-1-benzopyran-2-one. CAS Number: 2103919-91-9.
