Borneol

Japanese: ボルネオール
Borneol

1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol. C 10 H 18 O (154.25). Also called bornyl alcohol. Bicyclic monoterpene alcohol. Dextrorotatory (1 R, 2 S )-borneol is obtained from the Dryobalanops camphora tree, which grows in Borneo and Sumatra, and levorotatory (1 S, 2 R )-borneol, the antipode of borneol, is obtained from the Blumea balsamifera , which grows in Taiwan and the Malay Peninsula. Oxidation of (1 R, 2 S )-borneol produces d -camphor. Reduction of d -camphor with sodium and ethanol produces (1 R, 2 S )-borneol and its epimer with respect to the hydroxyl group, (1 R, 2 R )-isoborneol. (1R , 2S )-Borneol has a melting point of 208°C and a boiling point of 212°C. +37.7° (ethanol). It is easily soluble in ethanol, soluble in organic solvents, and insoluble in water. (1R , 2R )-Isoborneol has a melting point of 212°C. -32.3° (methanol). It is used in various cosmetics, fragrances, oral preparations, pharmaceutical fragrances, and disinfectants. [CAS 464-43-7: (1R , 2S )-Borneol]
