(E)-4-Methyl-2-{[Tris(Hydroxymethyl)Methyl]Iminomethyl}Phenolate

Abstract

In the zwitterionic title compound, C<inf>12</inf>H<inf>17</inf>NO <inf>4</inf>, 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.
