| Hazard Information | Back Directory | [Chemical Properties]
(1S)-(-)-alpha-Pinene is clear colourless liquid
| [Uses]
(1S)-(-)-alpha-Pinene is used in the preparation of hydroxy ketones such as hydroxycarvones.
| [Definition]
ChEBI: (-)-alpha-pinene is an alpha-pinene. It is an enantiomer of a (+)-alpha-pinene. | [General Description]
α-Pinene is a monoterpene used in industries like fragrance, pharmaceuticals, flavor, and cosmetics. It is a major component of pine oil and turpentine oil. Isomerization of α-pinene yields industrially important compounds like camphene, limonene, and p-cymene. | [reaction suitability]
reagent type: reductant | [storage]
Store at -20°C | [Purification Methods]
Purify as for 1R,5S--Pinene above. [Beilstein 5 III 366, 5 IV 455.] |
