    Description

    beta-Pinene (β-pinene) is a monoterpene, an organic compound found in plants. It is one of the two isomers of pinene, the other being α-pinene. It is colorless liquid soluble in alcohol, but not water. It has a woody-green pine-like smell.
    This is one of the most abundant compounds released by forest trees. If oxidized in air, the allylic products of the pinocarveol and myrtenol family prevail.
