Opticallly active adsorbents based on network polymerized derivative of dicarboxylic acids, diamines or diols which are chemically bonded to a carrier. The derivatives can be polymerized by radical polymerization or through hydrosilylation in the presence of a solid carrier. The optically active adsorbents are usable for chromatographic separation of racemic mixtures of enantiomers.

New 9-anthrylalkyl compounds having the general formula ##STR1## wherein R is hydrogen or an alkyl group, whereby, however, not more than one of the groups R is an alkyl group; R.sub.1 is hydrogen, lower alkyl, halogen or nitro; n is an integer of from 1 to 7, whereby, however, the total number of carbon atoms in the group --CHR--(CHR).sub.n -- does not exceed 8; and X is halogen, an azide group or a succinimidyl group. The new compounds are prepared from 9-anthrylalcohols which are reacted with a compound X--CO--X wherein X is a halogen, and then optionally with compounds giving azide or succinimidyl group. The compounds are used as derivatization reagents for separation and detection purposes. Intermediates for preparation of the above defined 9-anthrylalkyl compounds wherein one R is an alkyl group are 9-anthrylalcohols with the group --CHR--(CHR).sub.n --OH, wherein one R is an alkyl group.

Use of 9-anthrylalkyl compounds as derivatization reagents for

9-anthrylalkyl compounds

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.
