Application

Oxazosulfyl is primarily investigated as a novel sulfonylbenzoxazole scaffold for pesticidal activity research, particularly against lepidopteran pests. Its dual sulfonyl functionality makes it a candidate for studying metabolic resistance mechanisms in crop protection agents. Researchers utilize this compound in mode-of-action studies targeting insect nervous systems. The trifluoromethylsulfonyl moiety is of interest for structure optimization in next-generation agrochemicals.
