Metabolite Identification
Common NamePhthalimide
Descriptionphthalimide belongs to the class of organic compounds known as phthalimides. These are aromatic heterocyclic compounds containing a 1,3-dioxoisoindoline moiety. They are imide derivatives of phthalic anhydrides. Based on a literature review a significant number of articles have been published on phthalimide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phthalimide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phthalimide 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.
