In the title compound, Sofa C16H11BrO3, the molecules adopt an E configuration with respect to the C=C double bond of the propenone unit.The 13 non-H atoms of the benzodioxole and propenone units are approximately coplanar (r.m.s.deviation = 0.027 Å) and the bromobenzene ring plane forms a dihedral angle of 10.8 (1)° to this p
