Metabolite Identification
Common NameButanamide, N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]-
DescriptionButanamide, N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]-, also known as butyr-fentanyl or N-(1-phenylethyl)-4-piperidinyl)-N-phenylbutyramide, 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 very few articles have been published on Butanamide, N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]-. This compound has been identified in human blood as reported by (PMID: 31557052 ). Butanamide, n-phenyl-n-[1-(2-phenylethyl)-4-piperidinyl]- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Butanamide, N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]- 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.
