The molecule is a synthetic glycoside that consists of the branched hexasaccharide beta-D-Araf-(1->2)-alpha-D-Araf-(1->3)-[beta-D-Araf-(1->2)-alpha-D-Araf-(1->5)]-alpha-D-Araf-(1->5)-alpha-D-Araf having a 2-aminoethyl moiety at the reducing-end anomeric centre. It is a hexasaccharide derivative and a glycoside. It derives from a beta-D-Araf-(1->2)-alpha-D-Araf-(1->3)-[beta-D-Araf-(1->2)-alpha-D-Araf-(1->5)]-alpha-D-Araf-(1->5)-alpha-D-Araf.
