Etocyanozene

Etocyanozene (etocyanazene, 5-cyano-etodesnitazene) is a benzimidazole opioid 'desnitazene' derivative with opioid effects. It was first developed in the 1950s as part of the research that led to better-known compounds such as etonitazene. It is an analogue of etonitazene where the 5-nitro (NO₂) group has been replaced by a nitrile (C≡N) group.^[1] It is described as having "reduced but still significant" potency compared to etonitazene itself.^[2] It was made illegal in Germany in July 2021.^[3]
