Product Description: N-Aminofluorescein is a fluorescein hydrazide with spiro form, a highly selective and sensitive fluorescence probe for Cu2+. N-Aminofluorescein has no selective fluorescence response to other common metal ions, can be used for direct detection of Cu2+ in biological systems with λex/em=495/516 nm[1][2].
Formula: C20H14N2O4
