 | 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.]
