O-phosphorylated, and applied for reductiveamination of oligosaccharides. The dyes (ϵ≈20 000 m-1 cm-1 ) with six negative charges (pH≥8) and low m/z ratios enable labeling and fluorescencedetection of reducing sugars (glycans) related to the most structurally and functionally diverse class of natural products. Under excitation with a 488 nm laser, the new glycoconjugates emityellow light of about 560 nm,
