In the title compound, C9H13N3O4, an ester of the anti-infection drug secnidazole, the dihedral angle between the nitroimidazole mean plane (r.m.s. deviation = 0.028 Å) and the pendant acetate group is 43.17 (11)°. In the crystal, inversion dimers linked by pairs of C—HO interactions generate R22(10) loops and further C—HO hydrogen bonds link the dimers into [100] chains. Weak aromatic π–π stacking interactions with a centroid–centroid distance of 3.7623 (11) Å are also observed.

Crystal structure of 2-{[1-(2-methyl-5-nitro-1H-imidazol-1-yl)propan-2-yloxy]carbonyl}benzoic acid
In the title compound, C15H15N3O6, the dihedral angle between the planes of the benzene and imidazole rings is 34.93 (10)°. An intramolecular C—HO hydrogen bond is observed. In the crystal, O—HN hydrogen bonds link the molecules into chains parallel to the c axis.
