Use

Borneol is a bicyclic terpene alcohol. Borneol is an endo isomer; the corresponding exo isomer is isoborneol: Borneol occurs abundantly in nature as a single enantiomer or, less frequently, as the racemate. (1S,2R,4S)-(?)-Borneol occurs particularly in oils from Pinaceae species and in citronella oil. (1R,2S,4R)-(+)-Borneol is found, for example, in camphor oil (Ho-Sho oil), rosemary, lavender, and olibanum oils. Borneol is a colorless, crystalline solid. (+)-Borneol has a camphoraceous odor, with a slightly sharp, earthy, peppery note, which is less evident in (?)-borneol. Commercial borneol is often levorotatory ([α]20 D ?18 to ?28 in ethanol) and contains (?)-borneol and up to 40% isoborneol. Borneol is oxidized to camphor with chromic or nitric acid; dehydration with dilute acids yields camphene. Borneol is readily esterified with acids, but on an industrial scale, bornyl esters are prepared by other routes. For example, levorotatory borneol is synthesized industrially from levorotatory pinenes by Wagner–Meerwein rearrangement with dilute acid, followed by hydrolysis of the resulting esters. Borneol is used in the reconstitution of the essential oils in which it occurs naturally.
