Fenchol or 1,3,3-trimethyl-2-norbornanol is a monoterpenoid and an isomer of borneol. It is a colorless or white solid. It occurs widely in nature.
The naturally occurring enantiomere (1R)-endo-(+)-fenchol is used extensively in perfumery. Fenchol gives basil its characteristic scent,[2][3] and comprises 15.9% of the volatile oils of some species of Aster.[4]
It is biosynthesized from geranyl pyrophosphate via isomerization to linalyl pyrophosphate.[5]
Oxidation of fenchol gives fenchone.
