PIN: [(Ξ)-methyl(oxo){(1Ξ)-1-[6-(trifluoromethyl)pyridin-3-yl]ethyl}-λ6-sulfanylidene]cyanamide
IUPAC: [methyl(oxo){1-[6-(trifluoromethyl)-3-pyridyl]ethyl}-λ6-sulfanylidene]cyanamide
CAS: N-[methyloxido[1-[6-(trifluoromethyl)-3-pyridinyl]ethyl]-λ4-sulfanylidene]cyanamide
Reg. No.: 946578-00-3
Formula: C10H10F3N3OS
Activity: insecticides (sulfoximine insecticides)
Notes: Sulfoxaflor contains 2 tetrahedral stereogenic atoms (the sulfur atom, and the carbon atom attached to position 3 of the pyridine ring), and is a mixture of the 4 possible stereoisomers. Both (E)- and (Z)-isomers (involving the S=N double bond and the cyano group) exist, but they rapidly interconvert at ambient temperatures.
The bonding number of the sulfur atom is 6, but CAS uses additive nomenclature for the O= attached to the sulfur, and so the superscript to lambda is 4 in the CAS name.
