Chloromorphide (α-Chloromorphide) is an opiate analogue that is a derivative of morphine, where the 6-hydroxy group has been replaced by chlorine. Developed in 1952 in Germany, it is around 10x the potency of morphine.[1] It has similar effects to morphine such as sedation, analgesia and respiratory depression.

Chloromorphide is one of a series of opioids known as morphides and codides which are important precursors and intermediates in the synthesis of semi-synthetic opioid analgesic drugs, especially those with additions, substitutions, or other modifications at the 7, 8, and/or 14 position on the morphine carbon skeleton; semisynthetics with changes at other positions can also be made from these compounds. The codeine analogue of chloromorphide is alphachlorcodide (α-chlorocodide), an intermediate in one method of desomorphine sythesis which uses codeine as precursor.
