The herbicide was announced in March 2025 as a product of Chinese company Qingdao KingAgroot Chemical Compound Co., and was provisionally approved by the International Organization for Standardization.[2] It is noted as being effective against grasses and broadleaf weeds.[3] As of August 2025, it is not approved by any European regulatory authority.[1]
Production and synthesis
Flufenauxirim is produced through a substitution reaction between pyrimidine and an aromatic intermediate that is substituted with methoxy and fluorine groups.[1] A derivative of flufenauxirim is flufenauxirim-metotyl.[5]
