1-[(1'R,6'S)-2',2',6'-trimethylcyclohexyl]heptan-3-ol - highly diffusible amber fragrance with slight orris-like side note

Note that the C-3 position is epimeric, so this actually is a mixture of (1'R,3S,6'S) & (1'R,3R,6'S) isomers

Also note that the odor evaluation is for an ~95: 5 % ratio of trans/cis isomers.
