Metabolite Identification
Common Name2-Chloro-6-(1-piperazinyl)pyrazine
Description2-Chloro-6-(1-piperazinyl)pyrazine, also known as MK212 CPD or CPP, belongs to the class of organic compounds known as n-arylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an aryl group. Based on a literature review very few articles have been published on 2-Chloro-6-(1-piperazinyl)pyrazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-chloro-6-(1-piperazinyl)pyrazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Chloro-6-(1-piperazinyl)pyrazine 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.
