Sodium 2-(N-morpholino)ethanesulfonate monohydrate

J. R. Deschamps, J. L. Flippen-Anderson and C. George

Abstract: In this study, we report on the X-ray diffraction analysis of the common buffer salt sodium 2-(N-morpholino)ethanesulfonate (NaMES), Na·C₆H₁₂NO₄S·H₂O. MES is one of the `Good' buffers and is frequently used in biological and biochemical research. Following the method employed by Kunkel [(2000); Utilities for estimating the diffusion coefficients of weak electrolytes, URL: http://www.bio.umass.edu/biology/kunkel/probe/buffers/], the Stokes radius for this compound is 4.18  Å. This is significantly different from the value of 3.54  Å previously estimated from a molecular model.
