Common NameThioformamide
Descriptionmethanimidothioic acid belongs to the class of organic compounds known as thiocarboxylic acid amides. These are organic compounds containing an amide of thiocarboxylic acid, with the general structure R1C(=S)N(R2)R3 (R1-R3=H, alkyl, aryl). Based on a literature review a significant number of articles have been published on methanimidothioic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Thioformamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Thioformamide 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.
