| Hazard Information | Back Directory | [Chemical Properties]
(1R)-(+)-ALPHA-PINENE is Clear colourless liquid
| [Uses]
(1R)-(+)-α-Pinene is used in hydroboration reactions and the reduction of ketones. | [Definition]
ChEBI: The (+)-enantiomer of alpha-pinene. | [General Description]
(+)-α-Pinene is a monoterpenoid compound mainly found in Pinus species. | [Flammability and Explosibility]
Flammable | [Purification Methods]
(1R)-(+)-ALPHA-PINENE is isomerised by heat, acids and certain solvents. It should be distilled under reduced pressure under nitrogen and stored in the dark. It has been purified via the nitrosochloride [Waterman et al. Recl Trav Chim, Pays-Bas 48 1191 1929]. For purification of optically active forms see Lynn [J Am Chem Soc 91 361 1919].
