Metabolite Identification
Common NameFlephedrone
Description1-(4-fluorophenyl)-2-(methylamino)propan-1-one belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Based on a literature review very few articles have been published on 1-(4-fluorophenyl)-2-(methylamino)propan-1-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Flephedrone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Flephedrone 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.
