title: (E)-4-Methyl-2-{[tris(hydroxymethyl)methyl]iminiomethyl}phenolate.
abstract: In the zwitterionic title compound, C(12)H(17)NO(4), an intra-molecular N-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring. In the crystal structure, mol-ecules are linked by inter-molecular C-H⋯O and O-H⋯O inter-actions.
