Flufenauxirim is a chemical herbicide. It is a pyrimidinecarboxylic acid and a broad-spectrum herbicide. [1] [2] Its mechanism of action is unclear, but likely involves inhibition of enzymes that are involved in synthesis of fatty acids and amino acids. [1] The formula of flufenauxirim is C14H11F4N3O4. [3] [4]

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]
