Pseudomorphine (also known as oxydimorphine or dehydromorphine) is an inactive, natural dimerisation product of the morphine molecule in tandem and thus a common impurity in morphine concentrations. It was first described by Pelletier in 1835.[2]

This compound may be synthesized by the oxidative coupling of morphine by potassium ferricyanide.[1]
