Crystal structures of tolfenamic acid polymorphic forms I and II with precise hydrogen-atom positions for nuclear magnetic resonance studies

The structures of tolfenamic acid [TFA; 2-(3-chloro-2-methyl­anilino)benzoic acid, C(14)H(12)ClNO(2)] polymorph forms I and II have been redetermined [compare Andersen et al. (1989 ▸). J. Chem. Soc., Perkin Trans. 2, pp. 1443–1447] with improved precision using high-resolution X-ray diffraction data...
