| Hazard Information | Back Directory | [Uses]
Fenquinotrione is commonly involved in herbicidal mixtures and is commonaly used in soybean and cotton cultures. | [Production Methods]
Fenquinotrione is produced commercially through a triketone-type synthetic route that constructs its benzoxazinone herbicide framework. Industrial synthesis begins with preparation of a substituted benzoxazinone intermediate, typically derived from condensation of a hydroxyaniline with a diketone under controlled conditions. This fragment is then functionalised with trifluoromethyl and chloro substituents through selective halogenation and fluorination steps. The key intermediate is coupled with a triketone moiety via acylation, yielding the final compound. Purification is achieved by recrystallisation or chromatography to obtain technical-grade material. | [Mechanism of action]
