WebOct 26, 2024 · Chiral derivatizing agent (CDA) is an enantiomerically pure agent that converts each enantiomer into different diastereomers. This then allows NMR spectroscopy to identify the two diastereomers then trace back to the enantiomers [11]. One very versatile CDA is Mosher’s acid which is chiral and can exist as an (S) or an (R) enantiomer. WebSep 10, 2002 · Chiral separations using gas chromatography (GC) are mainly performed on chiral stationary phases (CSPs) capable of hydrogen bonding, coordination and inclusion, such as amino-acid derivatives, terpene-derived metal-coordination compounds and modified cyclodextrins, respectively.
