Flufenauxirim is a chemical herbicide. It is a pyrimidinecarboxylic acid and a broad-spectrum herbicide. Its mechanism of action is unclear, but likely involves inhibition of enzymes that are involved in synthesis of fatty acids and amino acids. The formula of flufenauxirim is C14H11F4N3O4. 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. It is noted as being effective against grasses and broadleaf weeds. As of August 2025, it is not approved by any European regulatory authority.
Production and synthesis Flufenauxirim is produced through a substitution reaction between pyrimidine and an aromatic intermediate that is substituted with methoxy and fluorine groups. A derivative of flufenauxirim is flufenauxirim-metotyl.
