OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132 Å); the molecule has non-crystallographic twofold molecular symmetry. This conformation is stabilized by two intramolecular O—H⋯N hydrogen bonds. The components of the crystal are connected by N—H⋯O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C—H⋯O contacts involving the DMSO H and urea carbonyl atoms, forming a supramolecular chain along the
c
axis. The chains associate
via
C—H⋯π interactions.
