<\/h3>\n

U-47700 (trans-3,4-dichloro-N-[2-(dimethylamino)cyclohexyl]-N-methylbenzamide)<\/strong>\u00a0represents a synthetic opioid compound originally developed by Upjohn Pharmaceuticals in the 1970s as part of a series of kappa-opioid receptor selective agonists. As a structural analog of AH-7921 with distinct pharmacological properties, U-47700 has emerged as a critical reference standard in forensic toxicology, opioid receptor pharmacology research, and novel psychoactive substance (NPS) monitoring programs.\u00a0Biosynlab<\/strong>\u00a0delivers analytical-grade U-47700 with certified \u226599.0% purity, supporting cutting-edge research across\u00a0USA (DEA-licensed institutions), United Kingdom, European Union, and international forensic and scientific markets<\/strong>.<\/p>\n

The unique trans-cyclohexyl-dimethylamino substitution<\/a> pattern combined with the 3,4-dichloro substitution on the benzamide ring creates a potent \u03bc-opioid receptor agonist with distinct structure-activity relationships compared to traditional morphinan opioids. This structural architecture has made U-47700 invaluable for comparative studies with other synthetic opioids including fentanyl, AH-7921, MT-45, and novel fentanyl analogs. Forensic laboratories in\u00a0London, Berlin, Amsterdam, New York, and Los Angeles<\/strong>\u00a0rely on Biosynlab U-47700 for quantitative analysis in post-mortem toxicology, driving under the influence investigations, and monitoring of the evolving synthetic opioid landscape.<\/p>\n

Chemical Properties & Structural Characterization<\/strong><\/h3>\n

U-47700<\/strong>\u00a0belongs to the benzamide chemical class, specifically the N-cyclohexyl-N-methylbenzamide subclass characterized by a diarylamide structure with cyclohexyl substitution and dichloro substitution on the aromatic ring.<\/p>\n
