HPLC of Formula: C3H8O2, Research speed reading in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 4254-15-3 In a document type is Article, and a compound is mentioned, 4254-15-3, Name is (S)-Propane-1,2-diol, introducing its new discovery.

The absolute configuration of 1,2-diols formed by a primary and a secondary (chiral) hydroxyl group can be deduced by comparison of the 1H NMR spectra of the corresponding (R)- and bis-(S)-MPA esters (MPA = methoxyphenylacetic acid). This method involves the use of the chemical shifts of substituents L1/L2 attached to the secondary (chiral) carbon, and of the hydrogen atom linked to the chiral center (Calpha-H) as diagnostic sig nais. Theoretical (AM1, HF, and B3LYP calculations) and experimental data (dynamic and low-temperature NMR spectroscopy, studies on deuterated derivatives, constant coupling analysis, circular dichroism (CD) spec tra, and NMR studies with a number of diols of known absolute configuration) prove that the signs of the DeltadeltaRS obtained for those signals correlate with the absolute configuration of the diol. A graphical model for the reliable assignment of the absolute configuration of a 1,2-diol by comparison of the NMR spectra of its bis-(R)- and bis-(S)-MPA esters is presented.
