4-Methyl-anilinium 2-carb-oxy-acetate.
During the formation of the title salt, C(7)H(10)N(+)·C(3)H(3)O(4) (-), an H atom of a carboxyl group was transferred to the amino group. All non-H atoms of the cation are essentially coplanar [r.m.s. deviation = 0.007 (4) Å]. The mean planes of the carboxyl-ate and carboxyl groups of the anion form a dihedral of 69.67 (1)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the anions and cations, forming a two-dimensional network parallel to the bc plane.
