In the title compound, C25H22BrN3O5S, the central benzene ring makes dihedral angles of 4.41 (10), 67.09 (9) and 62.05 (10)°, respectively, with the pyrazolone, bromobenzene and terminal phenyl rings. The dihedral angle between the pyrazolone and phenyl rings is 57.75 (11)°. In the crystal, two pairs of C—HO hydrogen bonds link the molecules into inversion dimers. A weak intramolecular C—HO hydrogen bonds is also observed.

In the title compound, C26H24BrN3O5S, the central benzene ring makes dihedral angles of 6.27 (6), 33.63 (6) and 69.31 (5)°, respectively, with the pyrazolone ring, the bromobenzene ring and the terminal phenyl ring. An intramolecular C—HO hydrogen bond occurs. The crystal packing features weak non-classical C—BrO interactions [BrO = 3.222 (2) Å] that form inversion-related dimers.
