Properties: Yellow-amber solid, mp 26-39°. d26 1.024. bp0.04 125°. Sol in xylene, methanol, less sol in aliphatic hydrocarbons. Soly in water <50 ppm. Stable in neutral or acidic solns; increases in pH or temp increases rate of hydrolysis. Fairly rapidly degraded in the soil. LD50 in male, female rats (mg/kg): 97, 61 orally; 237, 163 dermally (Gaines, Linder).
