The molecule is a disaccharide derivative that is 2,5-anhydro-D-glucitol in which the hydroxy group at position 3 has been glycosylated by a 2-O-sulfo-alpha-L-idopyranosyl group. It is a disaccharide derivative, a carbohydrate acid derivative and an oligosaccharide sulfate. It derives from a 2-O-sulfo-alpha-L-idopyranuronic acid.
