Pinocarveol

It is a bicyclic monoterpenoid, which is a combination of two isoprene units with one hydroxyl group as a substituent.

[1] It exists as either trans- or cis-pinocarveol, referring to stereochemical orientation of the oxygen as compared to the methylene bridge.

It is a naturally occurring molecule in numerous plant species including Eucalyptus globulus and Picea abies.

[3][4] Pinocarveol can be synthesized by heating a mixture of turpentine, selenium dioxide, and hydrogen peroxide.

The selenium dioxide acts as a catalyst while the hydrogen peroxide oxidizes the pinene found in turpentine.

NFPA 704 four-colored diamond Health 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g. sodium chloride Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuel Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
