| Common Name | Isoindolin-1-one |
|---|
| Description | Isoindolin-1-one, also known as 1-oxo-isoindoline or phthalimidine, belongs to the class of organic compounds known as isoindolones. These are aromatic polycyclic compounds that an isoindole bearing a ketone. Based on a literature review a significant number of articles have been published on Isoindolin-1-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isoindolin-1-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isoindolin-1-one 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. |
