Methyl 2,4-dihydroxy-5-(2-methylpropanamido)benzoate

In the title compound, C12H15NO5, the dihedral angle between the benzene ring and the C atoms of the terminal isopropyl group is 83.48 (16)°. Intramolecular N—H...O and O—H...O hydrogen bonds generate S(5) and S(6) rings, respectively. In the crystal, molecules are linked by O—H...O hydrogen bonds, generating C(7) chains propagating in [001]. Weak aromatic π–π stacking [centroid–centroid separation = 3.604 (3) Å] is also observed.
