2-(2-Isopropylanilino)pyridine-3-carboxylic acid
The asymmetric unit of the title compound, C15H16N2O2, contains two molecules and in each of the molecules, the two aromatic rings, lying in two different planes, are bridged by a secondary amino group. This might be due to steric hindrance caused by the isopropyl group.
