The title compound, C5H4N2O 4·H2O, a uracil derivative, contains several important functional groups, which give rise to its use in biomedical applications. The crystal structure consists of molecules held together by extensive intermolecular hydrogen bonding between neighbouring pyrimidine rings and between the acid groups and water molecules, resulting in a layered sheet structure. The asymmetric unit contains two molecules of the carboxylic acid and two water molecules.
