In the title molecule, C24H23N3O3S2, the benzothiadiazole ring system is essentially planar, with an r.m.s. deviation of 0.020 (8) Å. The thiophene and hydroxy-substitiuted rings form dihedral angles of 23.43 (9) and 35.45 (9)°, respectively, with the benzothiadiazole ring system. An intramolecular O—HN hydrogen bond is observed. In the crystal, weak C—HO hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 3.880 (3) Å] link molecules into chains along [100]. In addition, there are short SS contacts [3.532 (3) Å] which link these chains, forming a two-dimensional network parallel to (010).
