Metabolite Identification

Common Name

2-(2-Amino-1-hydroxyethyl)phenol

Description

2-(2-Amino-1-hydroxyethyl)phenol, also known as 2-octopamine, belongs to the class of organic compounds known as 1-hydroxy-4-unsubstituted benzenoids. These are phenols that are unsubstituted at the 4-position. Based on a literature review very few articles have been published on 2-(2-Amino-1-hydroxyethyl)phenol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(2-amino-1-hydroxyethyl)phenol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(2-Amino-1-hydroxyethyl)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.
