CAY10731

CAY10731 is a fluorescent probe for hydrogen sulfide (H2S). Upon reaction with H2S, fluorescein (FITC) is released and its fluorescence can be used to detect H2S. FITC displays excitation/emission maxima of 485/535 nm, respectively. CAY10731 is selective for H2S over glutathione (GSH), cysteine, H2O3-, SO3-, and H2O2 as well as tBuO and OH radicals. It has been used to detect H2S in rat hippocampal slices and nematodes.Formal Name: carbonic acid, 2-bromoethyl 6'-methoxy-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3'-yl ester.
