Like morphine-N-oxide, it was studied as a potential pharmaceutical drug and is considerably weaker than codeine. The amine oxides of this type form as oxidation products of the parent chemical; virtually every morphine/codeine class opioid has an equivalent nitrogen derivative such as hydromorphone-N-oxide.
