Synonyms: Urea, urea
Chemical formula: CO (NH2) 2
Organic chemical compound, carbonic acid diamide. As a result of condensation during heating creates a biuret.
It forms colorless crystals in the form of long, colorless, odorless needles, with a melting point of about 133 ° C, and undergoes decomposition before the boiling temperature is reached. It is hygroscopic, easily soluble in water.
