| Description | 2-(piperazin-1-yl)ethan-1-ol belongs to the class of organic compounds known as n-alkylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an alkyl group. Based on a literature review a small amount of articles have been published on 2-(piperazin-1-yl)ethan-1-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-(2-hydroxyethyl)piperazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-(2-Hydroxyethyl)piperazine 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. |
