Allophanic acid is the organic compound with the formula H2NC(O)NHCO2H. It is a carbamic acid, the carboxylated derivative of urea. Biuret can be viewed as the amide of allophanic acid. The compound can be prepared by treating urea with sodium bicarbonate: [1]
The anionicconjugate base, H2NC(O)NHCO2−, is called allophanate. Salts of this anion have been characterized by X-ray crystallography. [2] [3] The allophanate anion is the substrate for the enzyme allophanate hydrolase.
Allophanate esters arise from the condensation of carbamates.
