Abstract

In the title compound, C(8)H(10)N(4)O(2), all non-H atoms are nearly coplanar [maximum deviation 0.1256 (16) Å for the methyl C furthest from the ring]. Inter-molecular O-H⋯N hydrogen bonds link adjacent mol-ecules into a one-dimensional zigzag chain along the c axis. There is also a weak π-π stacking inter-action between neighbouring pyrazine rings, with a centroid-centroid distance of 4.0432 (15) Å.
