alpha-Pinene

Alpha-Pinene is a natural organic compound found in the oils of many species of many coniferous trees, notably the pine. It is one of the most common terpenoids in nature and contributes to the characteristic aroma of pine woods. In perfumery, it is valued for its fresh, piney scent.

Utilized in the creation of fresh, woody, and forest-like scents in perfumes and other fragranced products. Also serves as a starting material for the synthesis of other aroma chemicals.
