Description
Thiometon is the thion (P=S) analog of demeton-Smethyl.
It is a colorless oil, bp 104 ?C/0.3 mm Hg, vp
39.9 mPa (20 ?C). The water solubility is 200 mg/L (27 ?C).
It is highly soluble inmost organic solvents except alkanes.
Log Kow = 3.15. It is hydrolyzed in alkaline and acidic
media; DT50 (25 ?C) values at pH 3, 6, and 9 are 25, 27,
and 17 d, respectively.
