| Chemical Properties | (1S)-(-)-alpha-Pinene is clear colourless liquid
| | Uses | (1S)-(-)-alpha-Pinene is used in the preparation of hydroxy ketones such as hydroxycarvones.
| | Uses | (1S)-(-)-α-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. | | Purification Methods | Purify as for 1R,5S--Pinene above.
