(R)-1-[(S)-(3-Cyanothiomorpholino)carbonyl]-2-methylpropylaminium chloride dihydrate

In the title compound, C10H18N3OS+·Cl−·2H2O, the three C atoms of the isopropyl group are disordered and were refined using a split-site mode [occupancy ratio 0.53 (3):0.47 (3)]. In the crystal, the cations, anions and water molecules are connected via O—H⋯O, O—H⋯Cl, N—H⋯Cl and N—H⋯O hydrogen bonding.
