Metabolite Identification
Common Name6-Hydroxyazapropazone
Description6-Hydroxyazapropazone belongs to the class of organic compounds known as aminotriazines. These are organic compounds containing an amino group attached to a triazine ring. 6-Hydroxyazapropazone is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 6-hydroxyazapropazone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 6-Hydroxyazapropazone 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.
