Metabolite Identification
Common Name4-Morpholinopyridine
Description4-Morpholinopyridine belongs to the class of organic compounds known as dialkylarylamines. These are aliphatic aromatic amines in which the amino group is linked to two aliphatic chains and one aromatic group. Based on a literature review a significant number of articles have been published on 4-Morpholinopyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-morpholinopyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Morpholinopyridine 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.
