title: 8-Quinolyl 5-(dimethyl-amino)-naphthalene-1-sulfonate.
abstract: In the title compound, C(21)H(18)N(2)O(3)S, the dihedral angle between the naphthalene and quinoline ring systems is 55.53 (2)°, and the torsion angle involving the connecting C-S-O-C atoms is 87.60 (3)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into chains along [100] and there are π-π stacking inter-actions between pairs of chains with a centroid-centroid distance of 3.5485 (15) Å.
