Methyldesorphine

Methyldesorphine is an opioid analgesic. First synthesized in Germany in 1940 and patented in the US in 1952,[1] it has a high potential for abuse as with any potent opioid agonist, and is sometimes found along with desomorphine as a component of the home-made opioid mixture known as "Krokodil" used in Russia and the neighboring former Soviet republics.[2] It is approximately 15 times more potent than morphine as an analgesic[3][4] but if the 6-7 bond is saturated, the β isomer is some 50 times more potent than morphine.
