New methods for determining the enantiomeric purity of erythro-sphingosine
The enantiomeric purity of erythro-sphingosine samples can be determined simply, reliably, and accurately from 1H or 19F nuclear magnetic resonance spectra of the α-methoxy-α-(trifluoromethyl)phenylacetate (MTPA) derivative. As little as 0.1% of the minor enantiomer could be observed in a 1-mg sampl...
