| FENURON Usage And Synthesis |
| 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/kgLD50 oral (rabbit): 4700 mg/kgLD50 oral (guinea pig): 3200 mg/kg. |
