The title compound, C17H29NO4, contains a chiral center and crystallizes as a racemate. The asymmetric unit consists of two non-equivalent molecules, in which the carbethoxy groups have markedly different orientations [C(=O)CC(OEt)=O torsion angles = 59.3 (2) and 156.0 (2)°]. In the crystal, molecules form chains along [101] through N—HO hydrogen bonds.

In the title molecular salt, C6H9N2+·C7H4NO4−, the original pyridine N atom of 2-amino-4-methylpyridine is protonated and the carboxylic acid group of nitrobenzoic acid is deprotonated. In the crystal, the ions are linked by N—HO hydrogen bonds, forming chains propagating along [001]. The chains are linked via C—HO hydrogen bonds, forming two-dimensional networks lying parallel to the bc plane.
