在标题化合物C11H11BrO2S中，甲基亚砜基取代基的O原子和甲基位于苯并呋喃片段平面的两侧。非经典分子间C-H⋯O氢键和分子间C-Br⋯π相互作用稳定了晶体结构，其中C-Br⋯Cg = 3.629 Å （Cg为苯环质心）。此外，晶体结构表现出相邻分子呋喃环之间芳香π -π相互作用[质心-质心距离= 4.206 (6)Å]。
In the title compound, C11H11BrO2S, the O atom and the methyl group of the methylsulfinyl substituent are located on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by non-classical intermolecular C—H⋯O hydrogen bonding, and by intermolecular C—Br⋯π interactions, with C—Br⋯Cg = 3.629 Å (Cg is the centroid of the benzene ring). In addition, the crystal structure exhibits aromatic π–π interactions between the furan rings of neighbouring molecules [centroid–centroid distance = 4.206 (6) Å].
