| Hazard Information | Back Directory | [Chemical Properties]
White, crystalline solid.
Almost insoluble in water (0.3% at 25C), sparingly
soluble in hydrocarbon solvents, stable toward oxidation and moisture. | [Uses]
Fenuron is an phenylurea based herbicide used to control brush on chaparral watersheds. | [Definition]
electrum: 1. An alloy of gold andsilver containing 55–88% of gold.2. A German silver alloy containing52% copper, 26% nickel, and 22%zinc. | [Health Hazard]
Acute and chronic toxicity of low order;moderately toxic by intraperitoneal route; inthe body, it may hydrolyze to aniline, whichmay cause methemoglobinemia; the oralmedian lethal dose in experimental animalsranged between 3000 and 8000 mg/kg.
LD50 oral (rat): 6400 mg/kg
LD50 oral (rabbit): 4700 mg/kg
LD50 oral (guinea pig): 3200 mg/kg. |
