| Common Name | 4-(Methylamino)phenol |
|---|
| Description | 4-(Methylamino)phenol, also known as metol or N-methyl-4-hydroxyaniline, belongs to the class of organic compounds known as phenylalkylamines. These are organic amines where the amine group is secondary and linked on one end to a phenyl group and on the other end, to an alkyl group. Based on a literature review a significant number of articles have been published on 4-(Methylamino)phenol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-(methylamino)phenol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-(Methylamino)phenol 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. |
