The title compound, C17H17N5O, exists in the zwitterionic form with the amide group deprotonated. The mean planes of the 1,2,4-triazole and N-phenyl rings form a dihedral angle of 39.14 (8)°. The N atom of the amino group adopts a trigonal configuration. Intermoleculat C-H...O and C-H...N hydrogen bonds occur. In the crystal, molecules are linked into a two-dimensional network parallel to (10[\overline{1}]) by N-H...O and N-H...N hydrogen bonds. C-H...N contacts are also observed.
