The asymmetric unit of the crystal of the title compound (common name rivaroxaban), C19H18ClN3O5, contains two rivaroxaban molecules with different conformations; the C—C—N—C torsion angles between the oxazolidine and thiophene rings are −171.1 (7) and −106.8 (9)° in the two independent molecules. In the crystal, classical N—H...O hydrogen bonds and weak C—H...O hydrogen bonds link the molecules into a three-dimensional supramolecular architecture.
