Abstract Compound sodium N-(ethoxythioxomethyl)-β-alaninate (sodium 3- (ethoxycarbonothioyl) propanoate) was synthesized and characterized by IR, 1 H NMR, ESI- HRMS and single crystal X-ray diffraction. Single crystal X-ray diffraction analysis showed that the title compound crystallized in the triclinic space group P− 1 with cell parameters a= 10.142 (2) Å, b= 13.738 (3) Å, c= 15.751 (3) Å, α= 72.937 (2)°, β= 78.694 (2)°, γ= 89.999 (2 ...
