Crystal structure and Hirshfeld surface analysis of di­methyl 4-hy­dr­oxy-5,4?-di­methyl-2?-(toluene-4-sulfonyl­amino)­bi­phenyl-2,3-di­carboxyl­ate

In the title compound, C25H25NO7S, the molecular conformation is stabilized by intramolecular O—H?O and N—H?O hydrogen bonds, which form S(6) and S(8) ring motifs, respectively. The molecules are bent at the S atom with a C—SO2—NH—C torsion angle of ?70.86?(11)°. In the crystal, molecules are linked by C—H?O and N—H?O hydrogen bonds, forming molecular layers parallel to the (100) plane. C—H?? interactions are observed between these layers.
