| (1S)-(-)-Camphanic acid Usage And Synthesis |
| Chemical Properties | 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. |
| 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.] |
