In the title structure, C7H9N3O2·H2O, there are two formula units in the asymmetric unit.The molecule is a zwitterion, click here containing a quaternary N atom and a deprotonated carboxyl group, with C—O distances in the range 1.256 (2)–1.266 (3) Å.

The two independent molecules form a hydrogen-bonded R22(16) dimer about an approximate inversion center via N—H.O hydrogen bonds, with N.O distances of 2.766 (2) and 2.

888 (2) Å.O—H.O hydrogen bonds grandpas best involving the water molecules and additional N—H.O hydrogen bonds link these dimers, forming double chains.
