Isotocyanozene (5-cyano-isotodesnitazene) is a benzimidazole opioid analogue of isotonitazene which has been sold as a designer drug.^[1] It was first characterised by the drug checking service CanTEST, in September 2025 as an expected 'opioid' sample, and then later as an expected 'benzodiazepine' sample.^[2]^[3] Its μ-opioid in vitro activity is close to that of fentanyl.^[4] Following identification in human biological samples, isotocyanozene has been described to have opioid effects.^[5]
