- Odor description (10% DPG, blotter): dark
woody (woody facet of Cashmeran), agrestic odor
with slightly smoky aspects, and nuances of
vetiver and oud, and with slightly floral facets
(rosy in Mefrosol direction). The odor is more
floral and woody than that of the
(R)-enantiomer.

- Odor description (10% DPG, blotter): dark
woody, agrestic odor with fruity aspects in
Cashmeran direction and nuances of raspberry and
orris, and slightly rooty, oud and vetiver
facets, somewhat recalling epoxy cedrene. The
odor is sweeter and fattier than that of the
antipode.
