Metabolite Identification

Common Name

O-Methylhydroxylamine

Description

Methoxyamine belongs to the class of organic compounds known as organooxygen compounds. These are organic compounds containing a bond between a carbon atom and an oxygen atom. Based on a literature review very few articles have been published on Methoxyamine. This compound has been identified in human blood as reported by (PMID: 31557052 ). O-methylhydroxylamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically O-Methylhydroxylamine 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.
