Desomorphine (Dihydrodesoxymorphine, Permonid, also known as Krokodil) is an opiate analogue invented in 1932 in the United States, that is a derivative of morphine, where the 6-hydroxy group has been removed and the 7,8 double bond has been saturated. It has sedative and analgesic effects, and is around 8-10 times more potent than morphine. It was used in Switzerland under the brand name Permonid, and was described as having a fast onset and a short duration of action, with relatively little nausea or respiratory depression compared to equivalent doses of morphine. The traditional synthesis of desomorphine starts from α-chlorocodide, which is itself obtained by reacting thionyl chloride with codeine. By catalytic reduction, α-chlorocodide gives dihydrodesoxycodeine, which yields desomorphine on demethylation.
