An organyl group consisting of a hexasaccharide of N-formyl-alpha-D-perosamine residues linked sequentially (1->2), (1->3), (1->2), (1->2) and (1->2), and linked at the reducing end glycosidically to a 2-[2-(hexanamido)ethylamino]-3,4-dioxocyclobutylaminomethyl group used as a tether for conjugation to proteins.
