Abstract
The asymmetric unit of the title compound, C(12)H(17)NO(4)S, contains two molecules, both of which show disorder of the two terminal C atoms of the propyl chain over two sets of sites with an occupancy ratio of 0.581 (6):0.419 (6). Intramolecular C-H center dot center dot center dot O interactions help to establish the molecular conformations: in one molecule, the dihedral angle between the methyl ester group and the benzene ring is 41.0 (2)degrees, whereas in the other molecule it is 36.12 (17)degrees. In the crystal, molecules are linked by intermolecular C-H center dot center dot center dot O and CH center dot center dot center dot pi interactions.
