Common NamePyrazosulfuron-ethyl
Descriptionethyl 5-({[(4,6-dimethoxypyrimidin-2-yl)-C-hydroxycarbonimidoyl]amino}sulfonyl)-1-methyl-1H-pyrazole-4-carboxylate belongs to the class of organic compounds known as pyrazole carboxylic acids and derivatives. These are heterocyclic compounds containing a pyrazole ring in which a hydrogen atom is replaced by a carboxylic acid group. Based on a literature review very few articles have been published on ethyl 5-({[(4,6-dimethoxypyrimidin-2-yl)-C-hydroxycarbonimidoyl]amino}sulfonyl)-1-methyl-1H-pyrazole-4-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pyrazosulfuron-ethyl is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pyrazosulfuron-ethyl 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.
