title: N-(2,4,6-Trimethyl-phen-yl)maleamic acid.
abstract: The mol-ecular structure of the title compound, C(13)H(15)NO(3), is stabilized by a short intra-molecular O-H⋯O hydrogen bond within the maleamic unit. In the crystal, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into zigzag chains propagating in [010].
