(1S)-(-)-alpha-Pinene Chemical Properties,Uses,Production

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.

reaction suitability

reagent type: reductant

Purification Methods

Purify as for 1R,5S--Pinene above. [Beilstein 5 III 366, 5 IV 455.]
