In the title compound [systematic name: (3-chloro-2,6-dimethoxyphenyl)(ethoxyimino)methyl benzoate], C18H18ClNO5, the phenyl and chlorodimethoxyphenyl rings are linked by the ethoxyiminomethyl benzoate system such that they are almost perpendicular to each other with the dihedral angle between them being 85.72 (9)°. In the crystal, C-H...O and C-H...Cl hydrogen bonds between the phenyl and chlorodimethoxyphenyl rings generate R22(8) rings which link the molecules into zigzag chains along the b axis. Additional C-H...O contacts, together with weak intermolecular C-H...[pi] interactions, further link the molecules into a three-dimensional network.
