What is NEBURON?

Chemical properties

Crystalline solid; melts around 102 °C(215.6 °F); practically insoluble in water,48 mg/L at 24 °C (75.2 °F) (Merck 1996);slightly soluble in hydrocarbon solvents.

The Uses of NEBURON

Herbicide.

The Uses of NEBURON

Preemergence control of grasses and broad-leaved weeds in peas, beans, lucerne, garlic, beets, cereals, strawberries, ornamentals and forestry.

Definition

ChEBI: Neburon is a member of ureas.

Health Hazard

Acute oral toxicity is of very low order;moderately toxic by intravenous route.
LD50 oral (rat): 11,000 mg/kg
LD50 intravenous (mouse): 180 mg/kg.

Environmental Fate

Soil. Neburon undergoes dealkylation of the terminal nitrogen atom, ring hydroxylation and degradation to dichlorodihydroxyaniline (Hartley and Kidd, 1987). Residual activity in soil is limited to approximately 3 to 4 months (Hartley and Kidd, 1987).
Chemical/Physical. Neburon hydrolyzes under basic conditions forming aniline derivatives. The half-life of neburon in 0.50 N sodium hydroxide at 20°C is 167 days (El-Dib and Aly, 1976).
