Disurate

Disurate is a term that can refer to a few different concepts, primarily in chemistry and sometimes in colloquial or archaic usage. In chemistry, a disurate is a salt or ester of disuric acid. Disuric acid, also known as 5,5'-dihydroxybarbituric acid, is a heterocyclic organic compound that can be considered a derivative of barbituric acid. It contains two hydroxyl groups and exhibits tautomerism. Salts of disuric acid are formed when the acidic protons of the hydroxyl groups are replaced by metal cations. Esters are formed when these hydroxyl groups react with alcohols. These compounds have been studied for their chemical properties and potential applications, though they are not widely known or used in common industries.

The term "disurate" may also appear in older or less common chemical literature referring to derivatives of uric acid. Uric acid is a metabolic product found in the blood and urine of humans and other animals. Derivatives of uric acid, including certain salts and complexes, could historically have been referred to by less precise terminology that might include variations of "disurate" to indicate specific structural modifications or compound types. However, modern chemical nomenclature is more specific, and the term disurate is most accurately associated with derivatives of disuric acid. Its usage outside of specific chemical contexts is rare.
