The absolute configuration has been determined for the title compound, C 14 H 18 N 2 O 6 S, a fluorescent dipeptide analogue, which can act as a rigid backbone chromophore in peptides. Intermolecular N-HÁ Á ÁO C hydrogen bonds [HÁ Á ÁO = 2.37 (2) A ˚] are observed in the crystal packing.
The title compound, C~25~H~24~N~2~O~3~S~3~, was crystallized from a methanol–acetone mixture. The monoclinic structure features one molecule in the asymmetric unit. The crystal packing is stabilized by π stacking.
