    Product Description

    N-desethyl Fluetonitazene (DFNZ) (hydrochloride) (Item No. 41296) is an analytical reference standard categorized as an opioid.1 DFNZ is an active metabolite of fluetonitazene (FNZ; Item No. 40834) that acts as a highly potent μ-opioid receptor agonist. It produces analgesia in rodent models of acute and chronic pain without inducing respiratory depression, tolerance, or μ-opioid receptor downregulation after repeated dosing. DFNZ also has weaker reinforcing effects and increases dopamine neuron activity more slowly and to a lesser extent than FNZ in rodents. This product is intended for research and forensic applications.. This product is intended for research and forensic applications.
