C25H24F6N4  Form Yellow to tan crystals.  M.p. 189-191 °C  V.p. <0.0027 mPa (25 ºC); a value of <0.0008 mPa (45 ºC) has also been reported  KOW logP = 2.31  Henry 7.81 ´ 10-1 Pa m3 mol-1 (25 °C, calc.)  S.g./density 0.299 (25 °C)  Solubility In water 0.005-0.007 mg/l (25 ºC). In acetone 360, ethanol 72, 1,2-dichloroethane 170, methanol 230, isopropanol 12, xylene 94, chlorobenzene 390 (all in g/l, 20 ºC).  Stability When stored in original unopened container, stable in excess of 24 mo at 25 ºC, 12 mo at 37 ºC, and 3 mo at 45 ºC. Undergoes photolysis in sunlight (DT50 c. 1 h). DT50 in aqueous suspension (25 ºC) 24-33 d (pH 4.9), 10-11 d (pH 7.03), 11-12 d (pH 8.87). 
 
APPLICATIONS
Biochemistry Inhibits mitochondrial electron transport.
Mode of action Non-systemic insecticide with stomach action.
Uses Selective control of agricultural and household Formicidae (especially Camponotus, Iridomyrmex, Monomorium, Solenopsis and Pogonomyrmex spp. and Pheidole megacephala) using baits, and Blattellidae (especially Blatta, Blattella, Periplaneta and Supella spp.). Due to slow action, can be carried into nest by worker ants and kill the queen. Used at c. 16 g/ha per application.
Phytotoxicity No phytotoxicity observed.
Formulation types 95%TC 1%,2%GB
