Metabolite Identification
Common NameCarboxyfentanyl
DescriptionCarboxyfentanyl belongs to the class of organic compounds known as fentanyls. Fentanyls are compounds containing the fentanyl moiety or a derivative, which is based on a N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylpropanamide skeleton. Based on a literature review a small amount of articles have been published on Carboxyfentanyl. This compound has been identified in human blood as reported by (PMID: 31557052 ). Carboxyfentanyl is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Carboxyfentanyl 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.
