TY - JOUR A1 - Brüning, Jürgen A1 - Bats, Jan W. A1 - Schmidt, Martin Ulrich T1 - 2-Aminoterephthalic acid di­methyl ester T2 - Acta crystallographica. Section E, Structure reports online, 65.2009, S. o2468-o2469 N2 - Single crystals of the title compound, C10H11NO4, an inter­mediate in the industrial synthesis of yellow azo pigments, were obtained from the industrial production. The mol­ecules crystallize as centrosymmetic dimers connected by two symmetry-related N—H⋯O=C hydrogen bonds. Each mol­ecule also contains an intra­molecular N—H⋯O=C hydrogen bond. The dimers form stacks along the a-axis direction. Neighbouring stacks are arranged into a herringbone structure.
