Ethylmorphine

Ethylmorphine (also known as codethyline, dionine, and ethyl morphine) is an opiate narcotic analgesic.

Ethylmorphine was invented in Germany at Merck in 1884 and was used as a weaker alternative to heroin for all indications. Chemically, ethylmorphine is a morphine molecule with a -OC₂H₅ group substituted for the aromatic 3-OH group. Therefore, the closest chemical relative of ethylmorphine is codeine, also known as methylmorphine. Ethylmorphine also has a hydromorphone analogue (ethyldihydromorphinone or 3-ethoxy-7,8-dihydro-morphin-6-one), and a dihydromorphine analogue known as ethyldihydromorphine (CID:5492914), although none of them appears to be commercially distributed at the current time.
