    Product Description

    β-hydroxy Fentanyl (hydrochloride) (Item No. 20789) is an analytical reference standard that is structurally categorized as an opioid. It is more potent than fentanyl (Item Nos. ISO60197 | 14719) at the wild-type μ-opioid receptor in vitro (EC50s = 38.1 and 64.9 nM, respectively).1 This compound differs from the hydroxyproprionyl compound that has been described as a metabolite of fentanyl.2 The physiological and toxicological properties of β-hydroxy fentanyl are not known. This product is intended for research and forensic applications.

    WARNING This product is not for human or veterinary use.
