General description

Isoxaflutole is a novel pre-emergence herbicide widely employed for the protection of corn and sugarcane against broadleaf and grass weeds. Its mode of action involves the facilitation of characteristic foliar bleaching activity in target species preceding the plant death.

Application

Isoxaflutole may be used as an analytical reference standard for the determination of the analyte in blackcurrants and soya grain by gas chromatography-tandem mass spectrometry (GC-MS/MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), respectively.
