Metabolite Identification
Common Name1-Nitrosopiperazine
Description1-Nitrosopiperazine belongs to the class of organic compounds known as piperazines. Piperazines are compounds containing a piperazine ring, which is a saturated aliphatic six-member heterocyclic with two nitrogen atoms at positions 1 and 4, as well as four carbon atoms. 1-Nitrosopiperazine is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-nitrosopiperazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Nitrosopiperazine 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.
