A chiral derivatizing agent (CDA) also known as a chiral resolving reagent, is a chiral auxiliary used to convert a mixture of enantiomers into diastereomers in order to analyze the quantities of each enantiomer present within the mix. Analysis can be conducted by spectroscopy or by chromatography. The use of chiral derivatizing agents has declined with the popularization of chiral HPLC. Besides analysis, chiral derivatization is also used for chiral resolution, the actual physical separation of the enantiomers.

comment
  • Chirale Derivatisierungsreagenzien werden in der analytischen Chemie eingesetzt, um Stereoisomere oder Stereoisomerengemische (meist Enantiomerengemische) zu charakterisieren. Dabei wird ein Enantiomerengemisch mit dem enantiomerenreinen chiralen Derivatisierungsreagenz zur Reaktion gebracht. Diese Reaktion liefert Diastereomere, deren Verhältnis leicht analytisch (NMR, HPLC et cetera) bestimmt werden kann. Aus dem Diastereomerenverhältnis kann dann auf das Enantiomerenverhältnis in der zu untersuchenden Probe geschlossen werden. In der NMR-Spektroskopie werden die chiralen Derivatisierungsreagenzien auch chirale Verschiebungsreagenzien genannt.
