RESUMO
The title compound, C(13)H(13)N(5)O, crystallizes with two mol-ecules in the asymmetric unit. The crystal structure is stabilized by intra-molecular N-Hâ¯N and N-Hâ¯O hydrogen bonds. The dihedral angles between the pyrazine ring and the 4-aminolphenyl ring are 2.5â (1) and 6.5â (1)° in the two molecules.
