Description and Uses

2,4-Dihydroxypyridine belongs to the class of organic compounds known as pyridinones. Pyridinones are compounds containing a pyridine ring, which bears a ketone. This compound has been identified in human blood. 2,4-dihydroxypyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4-Dihydroxypyridine 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.

2,4-Dihydroxypyridine (3-deazauracil) was used in the synthesis of diazaphenoxathiin skeleton.
