In the title compound, C11H15NOS, the 3-(dimethylamino)prop-2-en-1-one Draw Reins unit is approximately planar [maximum deviation = 0.0975 (14) Å] and its mean plane of seven non-H atoms makes a dihedral angle of 6.96 (10)° with the thiophene ring.In the crystal, molecules are linked by pairs of C—H.O hydrogen bonds into inversion dimers with R22(14) ring motifs.

The dimers are stacked along the Timer Knob Coupling c axis through C—H.π interactions.The two methyl groups, attached to the thiophene ring and the amino N atom, are each disordered over two orientations, with site-occupancy ratios of 0.59 (4):0.41 (4) and 0.

74 (4):0.26 (4), respectively.
