Metabolite Identification

Common Name

Quinazolin-4-ylamine

Description

3,4-dihydroquinazolin-4-imine belongs to the class of organic compounds known as quinazolinamines. These are heterocyclic aromatic compounds containing a quianazoline moiety substituted by one or more amine groups. Based on a literature review very few articles have been published on 3,4-dihydroquinazolin-4-imine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Quinazolin-4-ylamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Quinazolin-4-ylamine 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.
