4254-15-3, Name is (S)-Propane-1,2-diol, belongs to chiral-oxygen-ligands compound, is a common compound. Quality Control of (S)-Propane-1,2-diolIn an article, once mentioned the new application about 4254-15-3.
1H NMR Spectra and Conformations of Propane-1,2-diol, meso- and Racemic Butane-2,3-diols, and some Alditols in Non-aqueous Media
The solvent change low polar->protic->very polar aprotic causes a progressive change in the conformation of the three title diols towards the conformer with the two C-O bonds trans.Alditols in deuterium oxide have each hydroxymethyl group with the C-O bond extending the chain as the main conformer.In polar aprotic solvents the main conformer has the C-O bond trans to the adjacent C-O bond.The carbon chain conformation can be somewhat different in the two solvent types.
