5-Chloro-3-cyclopentylsulfonyl-2-methyl-1-benzofuran

In the title compound, C14H15ClO3S, the cyclopenyl ring adopts an envelope conformation. In the crystal, molecules are linked by weak intermolecular C—H...O hydrogen bonds into dual chains propagating in [100]. The dual chains arise from pairs of the same or different hydrogen bonds between adjacent molecules
