Trichlorfon is a colorless crystalline powder.
It is soluble in water (120 g/L) and most organic solvents,
except aliphatic hydrocarbons. Log Kow = 0.43. Trichlorfon
is rapidly converted to dichlorvos by alkalis (2) and then
hydrolyzed; DT50 (22 ?C) values at pH 4, 7, and 9 are 510 d,
46 h, and <30 min, respectively.
