The molecule is a pyrrolizine alkaloid that is jacobine in which the tertiary amino function has been oxidised to the corresponding N-oxide. It has a role as a Jacobaea metabolite and an insecticide. It is a macrocyclic lactone, an organic heterotricyclic compound, a pyrrolizine alkaloid, a tertiary amine oxide, a tertiary alcohol and a spiro-epoxide. It derives from a jacobine.
