The Uses of Biuret
Analytical reagent, especially for proteins.
The Uses of Biuret
Biuret is used in protein assay. It is also used as Catalytic agent, Petrochemical additive. It is used in organic synthesis. Biuret (Carbamoylurea) was used as a source of dietary nitrogen in purified diets for steers.
Definition
A colorless crystalline organic compound made by heating UREA (carbamide). It is used in a chemical test for PROTEINS.
Definition
ChEBI: A member of the class of condensed ureas that is the compound formed by the condensation of two molecules of urea; the parent compound of the biuret group of compounds. Used as a non-protein nitrogen source in ruminant feed.
Agricultural Uses
Biuret is a compound formed from urea when the temperature during the manufacture of urea goes above 140 to 170°C. A biuret concentration of more than 2% in urea is harmful to plants as it affects the metabolism of proteins.
Purification Methods
Crystallise biuret from EtOH. [Beilstein 3 IV 141.]
