2-Aminoterephthalic acid dimethyl ester.

ABSTRACT: Single crystals of the title compound, C(10)H(11)NO(4), an inter-mediate in the industrial synthesis of yellow azo pigments, were obtained from the industrial production. The mol-ecules crystallize as centrosymmetic dimers connected by two symmetry-related N-H⋯O=C hydrogen bonds. Each mol-ecule also contains an intra-molecular N-H⋯O=C hydrogen bond. The dimers form stacks along the a-axis direction. Neighbouring stacks are arranged into a herringbone structure.
