(-)-(2R,4S)-Florol® - The second weakest in the series of Florol stereoisomers (odor threshold 520 ng/l air). Relatively weak, mainly fruity, grape-like, but also reminiscent of linalyl acetate and clary sage oil, with some nuances of dry herbs.

(+)-(2S,4R)-Florol® - Odorless on GC olfactometry (odor threshold >600 ng/l air). The weakest of all Florol stereoisomers. Very weak in odor, mainly linalool and coumarine like, with some citric and hesperidic nuances.

(+)-(2S,4S)-Florol® - Second most intense Florol stereoisomer (odor threshold 26 ng/l air), but already much weaker. Similar fresh-floral note as the enantiomer, but less sweet and also more linalool-type, more herbaceous, and more earthy in tonality.
