| Common Name | 2-Hydroxypyridine 1-oxide |
|---|
| Description | 2-Hydroxypyridine 1-oxide belongs to the class of organic compounds known as pyridinones. Pyridinones are compounds containing a pyridine ring, which bears a ketone. Based on a literature review a small amount of articles have been published on 2-Hydroxypyridine 1-oxide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-hydroxypyridine 1-oxide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Hydroxypyridine 1-oxide 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. |
