A branched amino octasaccharide derivative that is β-<small>D</small>-Man-(1→4)-β-<small>D</small>-GlcNAc-(1→4)-β-<small>D</small>-GlcNAc in which the mannosyl group is substituted at position 3 by a β-<small>D</small>-GlcNAc-(1→2)-[β-<small>D</small>-GlcNAc-(1→6)]-α-<small>D</small>-Man group, while the β-<small>D</small>-GlcNAc residue at the reducing end carries two α-<small>L</small>-Fuc residues via (1→3) and (1→6) linkages.
