CAS 108-19-0

Biureto

Descrizione:

Biureto, con il numero CAS 108-19-0, è un composto organico che è principalmente riconosciuto per il suo ruolo nella biochimica e nella chimica analitica. È un solido cristallino bianco solubile in acqua e presenta un punto di fusione intorno ai 132-134 °C. Biureto si forma attraverso la condensazione dell'urea ed è caratterizzato dalla presenza di due gruppi ammidici (-CONH-) collegati da un atomo di carbonio. Questa struttura consente a Biureto di formare complessi con ioni di rame, che è la base del test di Biureto, un metodo colorimetrico utilizzato per determinare la presenza di proteine in una soluzione. La reazione produce un colore viola caratteristico, che indica la presenza di legami peptidici. Biureto è anche utilizzato in varie applicazioni, tra cui fertilizzanti e come reagente in ambienti di laboratorio. Tuttavia, è importante maneggiare Biureto con cura, poiché può essere tossico ad alte concentrazioni. In generale, Biureto serve come un composto significativo sia in contesti industriali che di ricerca, in particolare nell'analisi delle proteine.

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.
