Urea
Urea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CO(NH2)2.
In many land animals, it is the main end product of the metabolism of nitrogen-containing compounds, and is excreted in the urine.
Animals produce urea in urea cycle.
Urea was discovered by Hilaire Rouelle in 1773. It was the first organic compound to be artificially synthesised in 1828 by Friedrich Woehler, who prepared it by the reaction of potassium cyanate with ammonium sulphate, thereby starting the discipline of organic chemistry
Its principal industrial use is the manufacture of plastics (specifically, urea-formaldehyde resin).
