Biuret is widely used in agriculture as a nitrogen fertilizer, particularly in urea-based fertilizers, to provide a slow-release source of nitrogen for plants. It is also employed in animal feed as a non-protein nitrogen source to enhance the protein content in ruminant diets. Additionally, biuret serves as a stabilizer in urea-formaldehyde resins, improving their durability and performance in adhesives and coatings. In biochemical research, it is utilized in the biuret test to detect the presence of proteins and peptides by forming a violet-colored complex with copper ions. Its applications extend to the production of flame retardants and as an intermediate in the synthesis of various organic compounds.
