(S)-(+)-Sulcatol - Both enantiomers of sulcatol were odoriferous to the human nose and smelled like geraniol with almost no difference in the odor as tested by the noses of the author (Mori) and his students

Racemic Sulcatol has also been described as: "Weak, sweet, oily-green; reminiscent of coriander" (Leffingwell & Associates, Flavor-Base 2007); "fresh, mild ethereal, oily, slightly herbal-fruity, floral connotation" (Boelens, PMP 2001); and "sweet oily green coriander" (Good Scents Co.)
