}}3-Carene is a bicyclic monoterpene consisting of fused cyclohexene and cyclopropane rings. It occurs as a constituent of turpentine,^[2] with a content as high as 42% depending on the source. Carene has a sweet and pungent odor.^[3], best described as fir needles, musky earth, and damp woodlands combination.^[4]

A colorless liquid, it is not soluble in water, but miscible with fats and oils.^[3] It is chiral, occurring naturally both as the racemate and enantio-enriched forms.

Reactions and uses

Treatment with peracetic acid gives 3,4-caranediol. Pyrolysis over ferric oxide induces rearrangement, giving p-cymene. Carene is used in the perfume industry and as a chemical intermediate.^[2]
