Metabolite Identification
Common Name9-methyl-9H-purine
Description9-methyl-9H-purine belongs to the class of organic compounds known as purines and purine derivatives. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring. Based on a literature review very few articles have been published on 9-methyl-9H-purine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 9-methyl-9h-purine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 9-methyl-9H-purine 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.
