CAS 108-19-0

Biuret

Description:

Biuret, with the CAS number 108-19-0, is an organic compound that is primarily recognized for its role in biochemistry and analytical chemistry. It is a white crystalline solid that is soluble in water and exhibits a melting point around 132-134 °C. Biuret is formed through the condensation of urea and is characterized by the presence of two amide groups (-CONH-) linked by a carbon atom. This structure allows biuret to form complexes with copper ions, which is the basis for the biuret test, a colorimetric method used to determine the presence of proteins in a solution. The reaction produces a characteristic violet color, indicating the presence of peptide bonds. Biuret is also used in various applications, including fertilizers and as a reagent in laboratory settings. However, it is important to handle biuret with care, as it can be toxic in high concentrations. Overall, biuret serves as a significant compound in both industrial and research contexts, particularly in protein analysis.

Biuret

CAS: 108-19-0

Biuret is a chemical compound that is used as an analytical reagent in the quantitative analysis of proteins. It is also used as a catalyst for the asymmetric synthesis of organic molecules. Biuret can be produced by the reaction of hydrochloric acid and methyl ethyl alcohol. The reaction solution formed from this process contains copper complex and biuret, which may then be separated using an analytical method such as FT-IR spectroscopy to determine the concentration of copper in the sample. Biuret has been shown to have high values when analyzed with FT-IR spectroscopy and is commonly used in analytical chemistry. Biuret reacts with proteins such as albumin, hemoglobin, and myoglobin to form protein-biuret complexes that are highly colored. This property allows it to be applied to biological samples for the detection of these proteins in urine, blood, or tissue samples. Biuret also catalyzes oxidation reactions by being reduced to hydrogen biurea on contact

Biuret (contains ca. 10% Triuret)

CAS: 108-19-0

Applications Biuret is used as a source of non-protein nitrogen in feed for ruminant. It is an impurity of urea based fertilizers as it has a poisonous effect on plants if present in high concentrations. Like peptide bonds, biuret forms violet-colored complexes with copper(II) ion in alkaline solution. This color change response is used to identify and quantify protein concentration (due to peptides present) and is known as biuret test.
