Description and Uses

Etrimfos is a colorless liquid, mp ?3.35 ?C, vp 6.5 mPa (20 ?C). Solubility in water is 40 mg/L (23–24 ?C). It is miscible with most organic solvents. Log Kow > 3.3. Neat etrimfos is unstable and degrades ca. 40% in 28 d at 50 ?C, but the dilute solutions in nonpolar solvents and its formulations are stable (about 5% loss in 1 y at ca. 20 ?C). It is hydrolyzed in aqueous media; DT₅₀ (25 ?C) at pH 3, 6, and 9 are 0.4, 16, and 14 d, respectively.

Satisfar is a pesticide sprayed on plants and vegetables as insecticide to fend off pests.
