Abstract: The title compound, anhydrous sodium (S)-(-)-6-methoxy--methyl-2-naphthaleneacetate, [Na(C₁₄H₁₃O₃)], has two independent molecules in the asymmetric unit, with structures closely related to that of the monohydrate. The most significant differences between the two molecules are in the O-C-C-C torsion angles, -10.4  (3) and -37.7  (3)°, of the side-chain carboxylate groups.
