Abstract
The two aromatic rings of the title compound, C11H11N3O, are nearly perpendicular to one another, with a dihedral angle between their planes of 80.52 (18)°. In the crystal, the amino N atom is a hydrogen-bond donor to the pyrazine N1atom of an inversion-related molecule and the hydroxy O atom is a hydrogen-bond donor to the pyrazine N4atom of another molecule. The two hydrogen bonds lead to the formation of a helical chain that runs along thebaxis.
