In the title structure, C7H9N3O2·H2O, there are two formula units in the asymmetric unit.The Deodorant molecule is a zwitterion, 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 Moses Basket Sheet hydrogen bonds, with N.O distances of 2.766 (2) and 2.888 (2) Å.O—H.
O hydrogen bonds involving the water molecules and additional N—H.O hydrogen bonds link these dimers, forming double chains.
