GRANULAR UREA
Urea or carbamide is an organic compound with the
chemical formula CO(NH2)2. The molecule has two —NH2
groups joined by a carbonyl (C=O) functional group.
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 a colorless, odorless solid, highly soluble in
water and practically non-toxic (LD50 is 15 g/kg for
rat). Dissolved in water, it is neither acidic nor
alkaline. The body uses it in many processes, the most
notable one being nitrogen excretion. Urea is widely
used in fertilizers as a convenient source of nitrogen.
Urea is also an important raw material for the chemical
industry.
The discovery by Friedrich Wöhler in 1828 that urea can
be produced from inorganic starting materials was an
important conceptual milestone in chemistry, as it
showed for the first time that a substance previously
known only as a byproduct of life could be synthesized
in the lab without any biological starting materials,
contradicting the widely held doctrine of vitalism.
