title: 3-Hy-droxy-1-[(morpholin-4-yl)meth-yl]pyridazin-6(1H)-one.
abstract: In the title compound, C9H13N3O3, the morpholine ring adopts a chair conformation and its mean plane makes a dihedral angle of 68.00 (11)° with the pyridazine ring. The carbonyl O atom deviates from the plane of the pyridazine ring by 0.0482 (12) Å. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, forming chains along [1-10].
