Metabolite Identification
Common Name1,2-Dihydroisoquinoline
Description1,2-dihydroisoquinoline belongs to the class of organic compounds known as aralkylamines. These are alkylamines in which the alkyl group is substituted at one carbon atom by an aromatic hydrocarbyl group. Based on a literature review very few articles have been published on 1,2-dihydroisoquinoline. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-dihydroisoquinoline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Dihydroisoquinoline 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.
