| Hazard Information | Back Directory | [Uses]
(-)-Camphene has been observed in the chemical composition of essential oils from different morphological parts of Pinus cembra L. | [Definition]
ChEBI: A camphene (2,2-dimethyl-3-methylenebicyclo[2.2.1]heptane) that has S configuration at position 1 and R configuration at position 4. | [Purification Methods]
Purify norbornane by fractionation through a Stedman column (see p. 11) at 100mm in a N2 atmosphere, crystallise it from EtOH and sublime it in a vacuum below its melting point. It is characterised by its camphenilone semicarbazone, m 217-218.5o, or camphor semicarbazone, m 236-238o. [NMR: Hana & Koch Chem Ber 111 2527 1978, Bartlett et al.
