Abstract: The chiral title compound, C₄H₁₀NO⁺·C₄H₅O₆^-·H₂O, is a hydrated molecular salt in which the tartaric acid has transferred one proton to the (S)-2-aminopropan-1-ol molecule. The crystal structure is stabilized by a three-dimensional network of N-HO and O-HO hydrogen bonds. The absolute configuration was assigned on the basis of the starting materials.
