WHITE TO SLIGHTLY BEIGE CRYSTALLINE POWDER | [Uses]
(1S)-(-)-Camphanic acid may be used in the preparation of (-)-(1S,4R)-camphanoyl chloride by reacting with thionyl chloride. | [Definition]
ChEBI: (-)-camphanic acid is a delta-lactone. | [General Description]
(1S)-(-)-Camphanic acid is commonly used as a chiral auxiliary for the separation of racemates. | [Purification Methods]
Dissolve it in CH2Cl2, dry (MgSO4), filter, evaporate and the residue is sublimed at 120o/0.5mm or 140o/1mm. [Gerlach Helv Chim Acta 61 2773 1978, Beilstein 18/8 V 101.] |
