Metabolite Identification
Common NameMetsulfuron-methyl
DescriptionMetsulfuron-methyl, also known as tribenuron-methyl, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Metsulfuron-methyl is an extremely weak basic (essentially neutral) compound (based on its pKa). Metsulfuron-methyl is a potentially toxic compound. Metsulfuron-methyl is a residual sulfonylurea herbicide that kills broadleaf weeds and some annual grasses. It is a systemic compound with foliar and soil activity, that inhibits cell division in shoots and roots. It has residual activity in soils, allowing it to be used infrequently but requiring up to 22 months before planting certain crops (sunflowers, flax, corn, or safflower). It has very low toxicity to mammals, birds, fish, and insects, but is a moderate eye irritant. This compound has been identified in human blood as reported by (PMID: 31557052 ). Metsulfuron-methyl is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Metsulfuron-methyl 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.
