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]

Because carene can be found in cannabis naturally, it can also be found in cannabis distillates. Greater concentrations of carene in a distillate give it an earthier taste and smell.[5] 3-Carene is also present in mango, giving the fruit a characteristic pine-like flavor and aroma.
