(Z)-Methyl 4-(1,3-benzothia-zol-2-yl-sulfan-yl)-2-(methoxy-imino)-3-oxo-butanoate.

In the mol-ecular structure of the title compound, C(13)H(12)N(2)O(4)S(2), there is a dihedral angle of 0.41 (13)° between the benzene and thia-zole rings. In the crystal, inversion dimers linked by two C-H⋯O inter-actions together with π-π stacking between the parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.673 (2) Å].
