Abstract
The invention relates to a new chiral reagent of the formula ##STR1## wherein X is halogen, an azide group or a succinimidyl group and wherein R is an alkyl group or a trifluormethyl group. The invention further relates to a method for the derivatization, determination and preparation resolution of primary and secondary amino-containing compounds. The method comprises the steps of derivatizing the amino function by the reagent to form diastereomeric carbamates, which are determined by e.g. fluorimetry or absorptiometry after separation by liquid chromatography.
