Abstract: In the title compound, C₁₂H₁₇NO₄S₂, the carboxyl groups link the molecules into centrosymmetric dimers through O-HO hydrogen bonds. An N-HO hydrogen bond between the NH group of the L-methionine unit and a neighbouring carboxyl group, together with a complementary C-HO contact to one O atom of the sulfonyl group, link the dimers into one-dimensional chains along the crystallographic b axis.
