In the title compound, C17H15NO5, carlsbad crush an intramolecular C—H.O hydrogen bond generates an S(6) ring motif.The benzene rings form a dihedral angle of 6.
45 (7)° with each other.In the crystal, vetality twist and lick inversion dimers linked by pairs of C—H.O hydrogen bonds generate R22(8) loops.
Adjacent dimers are further connected by C—H.O hydrogen bonds into an infinite chain along the [011] direction.
