Metabolite Identification
Common NameIndene
DescriptionIndene, also known as inden or indonaphthene, belongs to the class of organic compounds known as indenes and isoindenes. Indenes and isoindenes are compounds containing an indene moiety(which consists of a cyclopentadiene fused to a benzene ring), or a isoindene moiety (which consists of a cyclopentadiene fused to cyclohexadiene ring). Based on a literature review a significant number of articles have been published on Indene. This compound has been identified in human blood as reported by (PMID: 31557052 ). Indene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Indene 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.
