Metabolite Identification

Common Name

1,2-Diethyl-3-hydroxypyridin-4-one

Description

1,2-Diethyl-3-hydroxypyridin-4-one belongs to the class of organic compounds known as hydroxypyridines. These are organic compounds containing a pyridine ring substituted at one or more positions by a hydroxyl group. Based on a literature review very few articles have been published on 1,2-Diethyl-3-hydroxypyridin-4-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-diethyl-3-hydroxypyridin-4-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Diethyl-3-hydroxypyridin-4-one 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.
