Hazard InformationBack Directory
[Uses]

RPA 202248 is a derivative of isoxaflutole, a herbicide used for weed control.
[Definition]

ChEBI: 2-cyano-3-cyclopropyl-1-(2-mesyl-4-trifluoromethylphenyl)propan-1,3-dione is a beta-diketone and nitrile resulting from the the degradation of the isoxazole ring of isoxaflutole. The active herbicide of the proherbicide isoxaflutole. It has a role as a herbicide, an agrochemical and an EC 1.13.11.27 (4-hydroxyphenylpyruvate dioxygenase) inhibitor. It is a sulfone, an aromatic ketone, a member of cyclopropanes, a member of (trifluoromethyl)benzenes, a nitrile and a beta-diketone.
[Metabolism]

Studies have shown that RPA 202248 has a half-life of 103 days and degrades slowly and steadily to form RPA 203328 (2-methylsulfonyl-4-trifluoromethylbenzoic acid), which has no herbicidal activity.
