The two aromatic rings of the title compound, C(11)H(11)N(3)O, 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 N(1) atom of an inversion-related mol-ecule and the hy-droxy O atom is a hydrogen-bond donor to the pyrazine N(4) atom of another mol-ecule. The two hydrogen bonds lead to the formation of a helical chain that runs along the b axis. ...[more]
