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. WebOver the last decade, chiral liquid chromatography has made tremendous advances in selectivity and efficiency. These developments have been beneficial to many scientific disciplines especially in the field of high-throughput research.
