An optically active resolving agent

The Uses of (-)-Camphanic acid chloride

(1S)-(-)-Camphanic chloride is used as a resolving agent for alcohols as the diastereomeric esters by crystallization or chromatography and as a chiral derivatization reagent for determination of enantiomeric excess of alcohols and amines.

The Uses of (-)-Camphanic acid chloride

(1S)-(-)-Camphanic chloride may be used in esterification of enantiomers in volatiles releasedf from wheat, in order to determine the proportion of enantiomers and also in quantifying the esters.

General Description

(1S)-(-)-Camphanic chloride is a chiral derivatizing agent. It can be prepared by reacting (-)-(1S,4R)-camphanic acid with thionyl chloride.

Purification Methods

It is soluble in toluene (50g/100mL at 0o) and crystallises from pet ether (b 40-60o). It sublimes at 70o/5mm, Store it dry at 0o, max (CCl4) 1805s and 1780m cm-1. Armarego et al.
