A dry, sharp pine-forest note — cleaner, drier and more turpentine-like than alpha-pinene, with a resinous woody edge. Flashes off quickly leaving a faint dry coniferous trail.AI · claude-opus-4-7

Uses in perfumery

This Terpene is not used to any great extent as such in perfumes or flavors. As a chemical starting material or intermediate, it is one of the most important of all chemicals in the perfume industry.

Uses in flavor

The concentration used in flavors is equivalent to about 15 to 600 ppm in the finished consumer product.

Production

1) by isolation from American Turpentine (minor component). 2) it is also possible to convert alpha-Pinene into beta-isomer.
