Abstract (en)

[origin: WO2021198433A1] The invention relates to new kinds of water-soluble fluorescent dyes having high fluorescence quantum yield on the basis of oxygenic heterocyclic compounds, to the reactive derivatives and dye conjugates thereof and to use thereof for marking samples and for verifying analytes. The compounds of the novel dye class are compatible with commercial excitation light sources and are characterized by Stokes shifts of more than 50 nm.
