Common Name

2-Chloro-3-methylpyrazine

Description

2-Chloro-3-methylpyrazine, also known as (1-3,1-6)-beta-glucan or ha-beta-glucan, belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-member aromatic heterocycle, that consists of two nitrogen atoms (at positions 1 and 4) and four carbon atoms. Based on a literature review very few articles have been published on 2-Chloro-3-methylpyrazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-chloro-3-methylpyrazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Chloro-3-methylpyrazine 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.
