In the title compound, C29H37N5O4S2, two arms substituted with dansyl derivatives are connected to a central tertiary amine, where the dihedral angle between the planes of two dansyl units is 56.39 (4)°. Each arm contains a sulfonamide functional group and both N—H groups in the compound are pointed to the same side. The central part of the molecule is disordered over three sets of sites with a refined occupancy ratio of 0.547 (4):0.328 (4):0.125 (3). No intramolecular π–π or hydrogen-bonding interactions are observed. In the crystal, molecules are linkedviapairs of N—H...O interactions involving the same acceptor atom, forming inversion dimers.
