General Information
Catalog: BLP-010124
CAS: 3138-51-0
Molecular Formula: CH4N2[18O]
Molecular Weight: 62.06
Chemical Structure
Urea-[18O]
Description Labelled Urea. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals, and is the main nitrogen-containing substance in the urine of mammals. It is colorless, odorless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. Urea is widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry.
