Metabolite Identification

Common Name

2-(2-Aminoethyl)thiazole

Description

2-(2-Aminoethyl)thiazole, also known as 2-(2-thiazolyl)ethylamine or SK and F 7181 A2, belongs to the class of organic compounds known as 2-arylethylamines. These are primary amines that have the general formula RCCNH2, where R is an organic group. Based on a literature review a significant number of articles have been published on 2-(2-Aminoethyl)thiazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(2-aminoethyl)thiazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(2-Aminoethyl)thiazole 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.
