Urea

Urea, or carbamide, is an organic compound with the chemical formula (NH2) 2-C=O. Although mainly employed as a nitrogen fertilizer, it is also used in cattle and sheep feed and as an agent to reduce nitrogen oxide in diesel engine exhaust. Urea is also used to make certain thermosetting plastics such as urea-formaldehyde resins. Urea is produced on a commercial scale by synthesizing it from ammonia (NH3) and carbon dioxide (CO2).
