Metabolite Identification
Common Name3,4-Dichloroisocoumarin
Description3,4-Dichloroisocoumarin, also known as 3,4-DCI, belongs to the class of organic compounds known as isocoumarins and derivatives. These are polycyclic compounds containing an isochromane which bears a ketone at the carbon C1. Based on a literature review a significant number of articles have been published on 3,4-Dichloroisocoumarin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3,4-dichloroisocoumarin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3,4-Dichloroisocoumarin 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.
