In the crystal structure of the title compound, C5H11N3O, the C=N and C-N bond lengths in the CN3 unit are 1.2971 (14), 1.3595 (14) (NH2) and 1.3902 (13) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 115.49 (9)°, 119.68 (10)° and 124.83 (10)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. The morpholine ring is in a chair conformation. In the crystal, the molecules are linked by N-HN and N-HO hydrogen bonds, generating a three-dimensional network.
