| Common Name | 2-Amino-1,3,4-thiadiazole |
|---|
| Description | 2-Amino-1,3,4-thiadiazole, also known as aminothiadiazole, belongs to the class of organic compounds known as 2-amino-1,3,4-thiadiazoles. These are thiadiazoles with an amino group attached to the 2-position of a 1,3,4-thiadiazole ring. Based on a literature review very few articles have been published on 2-Amino-1,3,4-thiadiazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-amino-1,3,4-thiadiazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Amino-1,3,4-thiadiazole 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. |
