Biuret is 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.|Used as feed supplement for sheep and cattle since it is a good non-protein nitrogen source. In strongly alkaline solution biuret gives a violet color with copper sulfate.

Drug Information

MeSH：

Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)

MeSH Entry Terms：

Allophanamide

Biuret Use and Manufacturing

Methods of Manufacturing

Mix urea, water and disodium hydrogen phosphate and heat to dissolve. Raise the temperature to 150-160℃ and keep it warm for 2h. After the reaction was completed, the reaction was poured into water and left overnight. The crystal was filtered out as a crude product and recrystallized from dilute ammonia to obtain the finished biuret. In the production of urea, intermediate urine is used as the raw material, which is finished after high-temperature heat shrinkage, separation and drying.

Uses

1. Biuret is used in feed for ruminants, as feed additives as urea, like, but more safe than urea.
2. It is used as pharmaceutical intermediates, growth hormone, foaming agents, paints.
3. It is used for chemical analysis. Analytical reagent, especially for proteins.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 p
