Metabolite Identification
Common Name2-Azetidinone
Descriptionazetidin-2-one, also known as beta-propiolactam, belongs to the class of organic compounds known as cyclic carboximidic acids. These are organic acids with the general formula RC(=N)-OH (R=H, organic group), where the carboximidic acid group is part of a cycle. Based on a literature review a significant number of articles have been published on azetidin-2-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-azetidinone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Azetidinone 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.
