There are two independent molecules in the asymmetric unit of the title compound, C24H22N2O4S3. In each, the sulfonamide N atoms reveal nearly a trigonal-planar geometry with two S atoms of the O=S=O groups and one C atom of the thiazole ring; the angles around the N atoms are between 117.00 (13) and 123.86 (9)°. The methylphenylsulfonyl groups are in anti conformations, forming dihedral angles of 78.00 (7)/72.53 (5) and 77.09 (6)/71.50 (7)° with the trigonal S-N-S planes in the two molecules. The thiazole groups are rotated around the C-N bonds and are almost perpendicular to the S-N-S plane [dihedral angles of 78.00 (7)/72.53 (5) and 77.09 (6)/71.50 (7)°]. In the crystal, pairs of C-HO interactions, with the O atoms of the sulfonamide groups as acceptors, link each of the independent molecules into inversion dimers.
