Other names :
3,7,7-trimethyl bicyclo(4.1.0)hept-3-ene ; 3,7,7-trimethyl bicyclohept-3-ene ; 3,7,7-trimethyl-3-norcarene
Volatility :
Head
Uses in perfumery :
Used in spicy, woody and citrus notes, for a spicy effect. Mainly used in functionnal perfumery, in detergence and in masculine cosmetic products. Not so used in its isolated form.
Natural availability :
Often, the presence of a large quantity of Delta-3-Carene indicates the use of Black Pepper EO in a fragrance. Delta-3-Carene is also present in a large quantity in Indian Turpentine EO (55 to 65%), and to a lesser extent in Galbanum EO (2 to 16%), Angelica Root EO, Cypress EO, Firbalsam Absolute, Cedarwood Alaska EO and Blackcurrant Bud Absolute among others.
Year of discovery :
Data not available.
Other comments :
Delta-3-Carene is a monoterpene. This means, as for D-Limonene, that this molecule is composed of two isoprene units, and therefor ten carbon atoms and sixteen hydrogens. This category of terpenes includes many isomer.
Price Range :
€€
Stability :
Terpenes tend to polymerize under the effect of high oxydation, and are unstable in alkaline and acidic bases.

Synthesis route :
Delta-3-Carene is usually obtained naturally. Nevertheless, terpenes are often synthesized by Diels-Alder reactions, starting from Isoprene and reacting two types of molecules called diene (e.g. isoprene) and dienophile (molecule with a carbon double bond).
Synthesis precursor :
Delta-3-Carene is used in a synthesis way of L-Menthol. Delta-3-Carene is extracted from Indian Turpentine EO (contains 55 to 65%), to be then polymerized into trans-2,8-para-menthadiene. Isomerization, followed by hydrogenation and epoxidation are then necessary to obtain L-Menthol.
Isomerism :
Delta-3-Carene can either be levorotatory and dextrorotatory. In general, its racemic mixture is used in perfumery, as there is no major olfactory difference between the two enantiomers of the molecule.
