Metabolite Identification
Common NameCarbamimidothioic acid, methyl ester
Description(methylsulfanyl)methanimidamide 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 (methylsulfanyl)methanimidamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Carbamimidothioic acid, methyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Carbamimidothioic acid, methyl ester 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.
