Metabolite Identification
Common Names-Ethylisothiourea
DescriptionS-Ethylisothiourea belongs to the class of organic compounds known as isothioureas. These are organic compounds containing the isothiourea group, with the general structure R1SC(=NR2)N(R3)R4 (R1,R2,R3,R4=H, alkyl, aryl). Based on a literature review very few articles have been published on S-Ethylisothiourea. This compound has been identified in human blood as reported by (PMID: 31557052 ). S-ethylisothiourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically s-Ethylisothiourea 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.
