Aroma

Deteriorates when exposed to air, becomes semi-liquid, darkens in color and changes odor. Mild, rather sweet and very tenacious balsamic-woody odor with an almost floral undertone and a pepperiness which seem to be apparent only in impure material (possibly traces of hydrocarbons).

Chemical Properties

Crystalline solid. Insoluble in water; soluble in alcohol.

Uses

Guaiol is a component of guaiac wood oil, terpenol also found in cannabis.

Definition

A bicyclic sesquiterpene alcohol found in guaiac wood oil.

Production Methods

It can also be isolated from the wood of certain Australian members of the family Taxodiaceae, particularly the so-called "Murray River Pine".
