Used as a key intermediate in the synthesis of sulfoxaflor, a modern systemic insecticide effective against sap-feeding insects like aphids and whiteflies. Its structure enables selective action on insect nicotinic acetylcholine receptors while showing lower toxicity to non-target organisms. Also investigated for use in agrochemicals and pharmaceuticals due to its stable sulfonimidoyl group, which improves metabolic stability and bioavailability in active compounds.
