Common NameThiirane
Descriptionthiirane, also known as ethylene sulfide or thiacyclopropane, belongs to the class of organic compounds known as thiiranes. These are heterocyclic compounds containing a saturated three-member ring with two carbon atoms and one sulfur atom. Based on a literature review a significant number of articles have been published on thiirane. This compound has been identified in human blood as reported by (PMID: 31557052 ). Thiirane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Thiirane 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.
