Metabolite Identification
Common NameFuranylfentanyl
DescriptionN-phenyl-N-[1-(2-phenylethyl)piperidin-4-yl]furan-2-carboxamide belongs to the class of organic compounds known as 2-furanilides. These are aromatic heterocyclic compounds contaning a furan ring that is substituted at the 2-position with an anilide. Based on a literature review very few articles have been published on N-phenyl-N-[1-(2-phenylethyl)piperidin-4-yl]furan-2-carboxamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Furanylfentanyl is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Furanylfentanyl is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
