| Description | 2,2'-Dipyridylamine, also known as bis(2-pyridyl)amine, belongs to the class of organic compounds known as aminopyridines and derivatives. These are organic heterocyclic compounds containing an amino group attached to a pyridine ring. Based on a literature review a significant number of articles have been published on 2,2'-Dipyridylamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,2'-dipyridylamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,2'-Dipyridylamine 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. |
